Question 1

Why is my period late?

Femora · Accepted Answer

A late period can happen for many reasons, and it's usually not a cause for alarm. Here are the most common reasons:

Stress

When you're stressed, your body produces more cortisol, which can interfere with the hormones that regulate your menstrual cycle. This can delay ovulation and, as a result, your period.

Changes in weight

Significant weight loss or weight gain can affect your hormone levels. Being underweight or overweight can cause irregular periods or even cause them to stop temporarily.

Exercise

Intense physical activity - especially if you've recently increased your workout routine - can delay your period. This is common in athletes and those who exercise vigorously.

Hormonal birth control

Starting, stopping, or switching birth control methods can cause changes in your cycle. It may take a few months for your body to adjust.

Polycystic ovary syndrome (PCOS)

PCOS is a hormonal condition that can cause irregular or missed periods. If your periods are frequently late or irregular, it's worth discussing with your doctor.

Thyroid issues

Both an overactive thyroid (hyperthyroidism) and an underactive thyroid (hypothyroidism) can affect your menstrual cycle.

Pregnancy

If you're sexually active and your period is late, pregnancy is always a possibility. A home pregnancy test can help rule this out.

When to see a doctor

You should consult a healthcare provider if:
You've missed three or more periods in a row
Your periods are consistently irregular
You experience heavy bleeding or severe pain
You suspect you might be pregnant

Tracking your cycle with Femora can help you identify patterns and share accurate cycle data with your healthcare provider.

Question 2

What is ovulation?

Femora · Accepted Answer

Ovulation is the process where a mature egg is released from one of your ovaries. It's a key event in your menstrual cycle and the time when you're most fertile.

When does ovulation happen?

Ovulation typically occurs around the middle of your menstrual cycle. For a standard 28-day cycle, this is usually around day 14. However, the exact timing can vary from person to person and even from cycle to cycle.

What happens during ovulation?
Before ovulation: Your body increases production of estrogen, which causes the lining of your uterus to thicken. A rise in luteinizing hormone (LH) triggers the release of the egg.
During ovulation: A mature egg is released from the ovary into the fallopian tube. This is when conception can occur if sperm is present.
After ovulation: The empty follicle transforms into the corpus luteum, which produces progesterone to maintain the uterine lining. If the egg isn't fertilized, hormone levels drop and your period begins.

Signs of ovulation

Some people notice physical signs around ovulation:
A slight increase in basal body temperature
Changes in cervical mucus (it becomes clear and stretchy)
Mild pelvic pain or cramping on one side (called mittelschmerz)
Increased sex drive
Breast tenderness

The fertile window

Your fertile window spans about 6 days - the 5 days before ovulation and the day of ovulation itself. Sperm can survive in the reproductive tract for up to 5 days, which is why the days leading up to ovulation are also considered fertile.

Femora tracks your cycle phases including ovulation, helping you understand your fertility window and plan accordingly.

Question 3

What are the 4 phases of the menstrual cycle?

Femora · Accepted Answer

Your menstrual cycle is divided into four distinct phases, each with its own hormonal changes and effects on your body.
Menstrual Phase (Days 1-5)

This is your period - the phase most people are familiar with. The uterine lining sheds because pregnancy didn't occur in the previous cycle.

What happens:
The lining of the uterus is shed through the vagina
You may experience cramps, bloating, fatigue, and mood changes
Hormone levels (estrogen and progesterone) are at their lowest

Duration: Typically 3-7 days
Follicular Phase (Days 1-13)

This phase overlaps with menstruation and continues after your period ends. Your body begins preparing for the next potential pregnancy.

What happens:
The pituitary gland releases follicle-stimulating hormone (FSH)
Several follicles begin developing in your ovaries, each containing an egg
One follicle becomes dominant and continues to mature
Estrogen levels rise, causing the uterine lining to thicken
You may feel more energetic and have an improved mood

Duration: About 11-13 days (varies most between individuals)
Ovulation Phase (Day 14)

The shortest phase - this is when your body releases a mature egg.

What happens:
A surge in luteinizing hormone (LH) triggers the release of the mature egg
The egg travels down the fallopian tube toward the uterus
This is your most fertile time
You may notice clear, stretchy cervical mucus

Duration: 24-48 hours (the egg survives about 12-24 hours)
Luteal Phase (Days 15-28)

The final phase before your next period begins.

What happens:
The empty follicle transforms into the corpus luteum
Progesterone rises to maintain the uterine lining
If the egg isn't fertilized, the corpus luteum breaks down
Progesterone and estrogen drop, triggering PMS symptoms
Common symptoms: bloating, breast tenderness, mood changes, food cravings

Duration: Usually 12-14 days (the most consistent phase)

Femora's cycle ring dashboard shows you exactly which phase you're in, color-coded for easy reference: red for menstrual, pink for follicular, purple for ovulation, and indigo for luteal.

Question 4

What is PCOS?

Femora · Accepted Answer

Polycystic ovary syndrome (PCOS) is one of the most common hormonal disorders among women of reproductive age. It affects roughly 1 in 10 women and can have a significant impact on your menstrual cycle, fertility, and overall health.

What causes PCOS?

The exact cause isn't fully understood, but several factors play a role:
Excess androgens: Women with PCOS often produce higher-than-normal levels of male hormones (androgens), which can prevent ovulation and cause symptoms like acne and excess hair growth.
Insulin resistance: Many women with PCOS have insulin resistance, meaning their bodies can't use insulin effectively. This leads to higher insulin levels, which can increase androgen production.
Genetics: PCOS tends to run in families. If your mother or sister has PCOS, you may be more likely to develop it.
Inflammation: Research suggests that women with PCOS have a type of low-grade inflammation that stimulates the ovaries to produce androgens.

How does PCOS affect your cycle?

PCOS can cause:
Irregular periods: Cycles that are longer than 35 days or fewer than 8 periods per year
Missed periods: Some women with PCOS may go months without a period
Heavy bleeding: When periods do occur, the uterine lining has had more time to build up, so bleeding may be heavier

Diagnosis

PCOS is typically diagnosed when you have at least two of these three criteria:
Irregular or absent periods
Signs of excess androgens (acne, excess hair growth) or blood tests showing high androgen levels
Polycystic ovaries visible on ultrasound (many small follicles on the ovaries)

Treatment

While there's no cure for PCOS, symptoms can be managed through:
Lifestyle changes (healthy diet, regular exercise, maintaining a healthy weight)
Hormonal birth control to regulate periods
Medications to manage specific symptoms
Fertility treatments if you're trying to conceive

When to see a doctor

Talk to your doctor if you experience irregular periods, difficulty getting pregnant, or signs of excess androgen levels. Early diagnosis and management can help reduce the risk of long-term complications.

Tracking your cycle with Femora can help you identify irregular patterns early and provide your healthcare provider with detailed cycle data for more accurate diagnosis.

Question 5

What are the symptoms of PCOS?

Femora · Accepted Answer

PCOS symptoms can vary widely from person to person. Some women have mild symptoms, while others experience several that significantly affect their daily life. Here are the most common signs to watch for.

Menstrual irregularities
Irregular periods: Cycles longer than 35 days or shorter than 21 days
Missed periods: Going two or more months without a period
Heavy periods: Unusually heavy bleeding during periods
Unpredictable cycles: Difficulty knowing when your next period will come

Skin and hair changes
Excess hair growth (hirsutism): Unwanted hair on the face, chin, chest, back, or abdomen - affects up to 70% of women with PCOS
Acne: Persistent acne on the face, chest, or upper back, often beyond the teenage years
Oily skin: Increased oil production leading to frequent breakouts
Hair thinning: Thinning hair on the scalp, similar to male-pattern baldness
Skin darkening: Dark patches of skin in body creases (neck, groin, under breasts) - called acanthosis nigricans

Weight and metabolism
Weight gain: Particularly around the abdomen
Difficulty losing weight: Even with diet and exercise
Insulin resistance: Your body struggles to use insulin effectively, which can lead to higher blood sugar levels

Reproductive symptoms
Difficulty getting pregnant: PCOS is one of the leading causes of infertility
Multiple ovarian cysts: Small fluid-filled sacs on the ovaries (visible on ultrasound)

Emotional and mental health
Mood swings: More pronounced emotional changes
Anxiety and depression: Higher rates compared to women without PCOS
Fatigue: Persistent tiredness, often linked to insulin resistance
Sleep problems: Including sleep apnea

Other symptoms
Headaches (due to hormonal changes)
Pelvic pain
Inflammation

Important to know
You don't need to have all symptoms to have PCOS
Symptoms can change over time
Many symptoms overlap with other conditions, so proper diagnosis is essential
Symptoms can be managed effectively with the right treatment plan

When to seek help

If you notice several of these symptoms - especially irregular periods combined with acne, excess hair growth, or difficulty managing your weight - schedule an appointment with your healthcare provider.

Use Femora to track your cycle patterns, symptoms, and flow intensity. Having detailed data about your menstrual history makes it easier for your doctor to assess whether PCOS could be a factor.

Question 6

What is vaginal discharge?

Femora · Accepted Answer

Vaginal discharge is a fluid produced by glands inside your vagina and cervix. It plays an important role in keeping your reproductive system healthy.

What does discharge do?

Discharge serves several essential functions:
Cleans the vagina - It carries away dead cells and bacteria, acting as the vagina's natural self-cleaning mechanism
Prevents infection - The fluid maintains an acidic environment (pH 3.8–4.5) that discourages harmful bacteria and yeast from growing
Provides lubrication - It keeps vaginal tissues moist and comfortable
Supports reproduction - During ovulation, discharge changes to help sperm travel toward the egg

What's normal?

Normal discharge varies from person to person, but generally:
Color: Clear to milky white
Texture: Can range from thin and watery to thick and sticky, depending on where you are in your cycle
Amount: About 1–4 ml per day (roughly half a teaspoon), though this can increase around ovulation, during pregnancy, or with sexual arousal
Smell: Mild or no odor - it should not smell foul or fishy

What produces discharge?

Discharge comes from two main sources:
Cervical glands - Produce mucus that changes in consistency throughout your cycle
Vaginal walls - Produce a transudate (fluid that seeps through the tissue) that helps with lubrication

The balance of estrogen and progesterone throughout your menstrual cycle directly influences the amount and type of discharge you produce.

Tracking your symptoms with Femora can help you notice patterns in your discharge throughout your cycle.

Question 7

Is vaginal discharge normal?

Femora · Accepted Answer

Yes - vaginal discharge is completely normal and is actually a sign that your reproductive system is working properly. Almost all women of reproductive age experience some amount of discharge.

Why it's normal

Your vagina is a self-cleaning organ. Discharge is the mechanism it uses to:
Flush out old cells from the vaginal lining
Maintain a healthy pH balance
Keep harmful bacteria and infections at bay
Provide natural lubrication

How much is normal?

Most people produce about 1 to 4 ml of discharge per day. However, the amount can naturally increase during:
Ovulation - Estrogen peaks, producing more clear, stretchy discharge
Sexual arousal - Additional lubrication is produced
Pregnancy - Hormonal changes increase discharge significantly
Exercise - Physical activity can temporarily increase discharge
Hormonal birth control - Some methods can change discharge patterns

When discharge is normal

Your discharge is likely healthy if it:
Is clear, white, or slightly off-white
Has a mild or neutral smell
Doesn't cause itching, burning, or irritation
Changes in consistency throughout your cycle (this is expected!)

When to pay attention

While discharge itself is normal, certain changes may need medical attention:
Sudden change in color (yellow, green, gray)
Strong, unpleasant, or fishy odor
Cottage cheese-like texture with itching (possible yeast infection)
Accompanied by pain, burning, or irritation

Use Femora to log your daily symptoms and track changes in your body throughout your cycle.

Question 8

Why does discharge change during the menstrual cycle?

Femora · Accepted Answer

Your discharge changes throughout your menstrual cycle because of fluctuations in estrogen and progesterone. These hormonal shifts directly affect the cervical mucus your body produces.

Discharge by cycle phase

Menstrual phase (Days 1–5)
Discharge is mixed with menstrual blood
You may not notice separate discharge during this time

Post-period / Early follicular (Days 6–9)
Minimal discharge - You may feel relatively dry
What's there is typically thick, sticky, or pasty
Color: white or slightly cloudy

Pre-ovulation / Late follicular (Days 10–13)
Discharge increases as estrogen rises
Becomes thinner, more watery, and creamy
Color: white to slightly cloudy

Ovulation (Days 14–16)
Peak discharge - this is when you'll notice the most
Clear, stretchy, and slippery - often compared to raw egg whites
This "fertile mucus" is designed to help sperm survive and travel
You may notice it when wiping or on underwear

Post-ovulation / Luteal phase (Days 17–28)
Progesterone rises, making discharge thicker and stickier again
Amount decreases compared to ovulation
Color: white or cloudy
Becomes minimal just before your period starts

Why these changes happen
Estrogen (rises before ovulation) → thinner, wetter, more abundant discharge
Progesterone (rises after ovulation) → thicker, stickier, less discharge

These changes are your body's way of either supporting potential fertilization (around ovulation) or creating a protective barrier (during the luteal phase).

Why tracking matters

Understanding your discharge patterns can help you:
Identify your fertile window
Notice if something unusual is happening
Have more informed conversations with your healthcare provider

Femora tracks your cycle phases automatically, so you always know which phase you're in and what to expect.

Question 9

What does white discharge mean?

Femora · Accepted Answer

White discharge is one of the most common types, and in most cases, it's completely normal. However, the texture and accompanying symptoms matter.

Normal white discharge

Thin and smooth
Common throughout your cycle
Increases slightly before and after ovulation
Sign of a healthy vagina

Thick and creamy
Typical during the luteal phase (after ovulation, before your period)
Caused by higher progesterone levels
Completely normal

Thick and sticky
Common right after your period ends
Your body is producing less cervical mucus at this point

When white discharge may be a concern

Cottage cheese-like texture
Thick, clumpy, white discharge resembling cottage cheese
Accompanied by itching, burning, or redness
This is a classic sign of a yeast infection (vaginal candidiasis)
Very common - about 75% of women experience at least one yeast infection
Usually treated with over-the-counter antifungal medication

Thin, white-gray with a fishy smell
May indicate bacterial vaginosis (BV)
BV occurs when the natural balance of bacteria in the vagina is disrupted
Requires treatment with prescription antibiotics

What's the bottom line?
White discharge without other symptoms = normal
White, clumpy discharge + itching = likely yeast infection
White-gray discharge + fishy odor = possibly BV

If you're unsure, tracking your symptoms and discussing them with your healthcare provider is always a good idea.

Log your symptoms daily in Femora to spot patterns and share accurate data with your doctor.

Question 10

What does yellow or green discharge mean?

Femora · Accepted Answer

While a very pale yellow can be normal, bright yellow or green discharge is usually a sign that something needs attention.

When pale yellow is normal
Light yellow discharge can simply be normal discharge that has been exposed to air and oxidized slightly
If it's mild in color, has no strong odor, and causes no irritation, it's likely fine
Some people naturally have discharge with a slight yellowish tint

When yellow or green is a concern

Bright yellow or yellow-green discharge
This may indicate:
Bacterial vaginosis (BV) - Along with a fishy smell, especially after sex
Trichomoniasis - A sexually transmitted infection (STI) that causes frothy, yellow-green discharge with a strong odor, along with itching and irritation
Chlamydia or gonorrhea - STIs that can cause yellowish discharge, often with pain during urination or pelvic pain

Green discharge
Green discharge is generally not normal and often suggests:
An active infection - Usually bacterial or an STI
Trichomoniasis - One of the most common causes of green, frothy discharge

Accompanying symptoms to watch for

See a doctor if yellow or green discharge comes with:
Strong or foul odor
Itching, burning, or irritation
Pain during urination or sex
Pelvic or lower abdominal pain
Fever

What to do
Don't self-diagnose - The color alone doesn't tell the full story
See your doctor - A simple swab test can identify the cause
Don't douche - This can worsen infections by disrupting your vaginal flora
Complete any prescribed treatment - Even if symptoms improve before you finish

Track any unusual symptoms in Femora's daily log so you have a clear record to share with your healthcare provider.

Question 11

What does brown discharge mean?

Femora · Accepted Answer

Brown discharge is usually old blood that has taken longer to leave your body. In most cases, it's normal and nothing to worry about.

Common causes (normal)

Before or after your period
Most common cause - Brown discharge at the start or end of your period is simply old blood mixed with discharge
Blood turns brown when it oxidizes (is exposed to air), which happens when it takes longer to exit the body
Completely normal and very common

Ovulation spotting
Some people experience light spotting around ovulation
This can appear as brown or pinkish-brown discharge
Caused by the slight hormonal shift when the egg is released

Implantation bleeding
Light brown or pinkish spotting about 10–14 days after conception
Occurs when a fertilized egg implants in the uterine lining
Usually lighter and shorter than a normal period

Birth control
Hormonal contraceptives (pills, IUDs, implants) can cause breakthrough bleeding
This often appears as brown spotting between periods
More common in the first few months of starting or switching methods

Less common causes (may need attention)

Infections
Some vaginal infections can cause brown discharge
Usually accompanied by odor, itching, or pain

Cervical irritation
After a pap smear, sexual intercourse, or pelvic exam
The cervix is sensitive and can bleed lightly

Polycystic ovary syndrome (PCOS)
Irregular periods from PCOS can cause occasional brown spotting

When to see a doctor

Consult your healthcare provider if brown discharge:
Occurs frequently between periods without explanation
Is accompanied by pain, fever, or foul odor
Happens after menopause
Lasts longer than a few days

Logging spotting and discharge in Femora helps you identify whether it's a regular pattern or something to discuss with your doctor.

Question 12

Is discharge during ovulation normal?

Femora · Accepted Answer

Absolutely - increased discharge during ovulation is not only normal, it's one of your body's most reliable signs that ovulation is happening.

What ovulation discharge looks like

During ovulation, your discharge typically becomes:
Clear - Almost transparent
Stretchy - You can stretch it between your fingers (sometimes called "spinnbarkeit")
Slippery - Similar in texture to raw egg whites
Abundant - This is usually when you produce the most discharge in your cycle

Why it happens

As you approach ovulation, estrogen levels peak. This signals your cervix to produce a specific type of mucus that:
Creates a sperm-friendly environment - The alkaline mucus neutralizes the vagina's natural acidity
Helps sperm travel - The stretchy, watery texture acts like a highway for sperm to reach the egg
Keeps sperm alive longer - Sperm can survive up to 5 days in fertile cervical mucus

The timeline
Days before ovulation: Discharge gradually becomes wetter and more slippery
Day of ovulation: Peak clear, stretchy, egg-white discharge
After ovulation: Discharge quickly becomes thicker and stickier as progesterone rises

How to use this information

Tracking your discharge can help you:
Identify your fertile window - The appearance of egg-white cervical mucus is one of the best natural indicators of fertility
Confirm ovulation occurred - The shift from wet/stretchy to dry/thick signals that ovulation has passed
Understand your body better - Knowing what's normal for you makes it easier to spot when something is off

Is more discharge during ovulation a problem?

No. Some people produce quite a lot of discharge during ovulation, and that's perfectly normal. You might notice it on your underwear or when wiping. If it bothers you, a panty liner can help with comfort.

Femora automatically tracks your ovulation phase based on your cycle data, so you'll know exactly when to expect these changes.

Question 13

When should I worry about discharge?

Femora · Accepted Answer

While discharge is normal, certain changes can signal an infection or other condition that needs medical attention. Here's how to tell the difference.

Warning signs to watch for

Changes in color
Bright yellow, green, or gray discharge is often a sign of infection
Brown or bloody discharge outside your period (especially after menopause) should be evaluated

Changes in smell
A strong, fishy odor - especially after sex - may indicate bacterial vaginosis
Foul or unusually unpleasant smell that's different from your normal scent

Changes in texture
Cottage cheese-like (thick, white, clumpy) - classic yeast infection sign
Frothy or foamy - may suggest trichomoniasis

Accompanying symptoms
Itching or burning in or around the vagina
Redness or swelling of the vulva
Pain during urination or sex
Pelvic pain or lower abdominal discomfort
Bleeding between periods or after sex

Common conditions and their discharge patterns

| Condition | Discharge | Other symptoms |
|-----------|-----------|----------------|
| Yeast infection | Thick, white, clumpy | Itching, burning, redness |
| Bacterial vaginosis | Thin, gray-white, fishy smell | Odor worsens after sex |
| Trichomoniasis | Yellow-green, frothy | Itching, pain during urination |
| Chlamydia/Gonorrhea | Yellow or cloudy | May have no other symptoms |

What to do
Don't panic - Most discharge changes are easily treatable
Don't douche - This disrupts healthy bacteria and can worsen infections
See your doctor - A simple exam and swab test can identify the cause
Track your symptoms - Note when changes started, what they look like, and any other symptoms

When to seek urgent care

See a doctor promptly if you have:
Fever along with abnormal discharge
Severe pelvic pain
Discharge after unprotected sex with a new partner
Discharge with bleeding that isn't your period

Daily symptom logging in Femora helps you track changes over time, making it easier to give your healthcare provider accurate information.

Question 14

Can stress affect vaginal discharge?

Femora · Accepted Answer

Yes - stress can absolutely affect your vaginal discharge. Since your reproductive system is closely linked to your hormonal and immune systems, stress can influence both the amount and type of discharge you produce.

How stress affects discharge

Hormonal disruption
Stress triggers the release of cortisol (the stress hormone)
Elevated cortisol can interfere with estrogen and progesterone levels
Since these hormones directly control cervical mucus production, stress can change your discharge patterns
You might notice more discharge, less discharge, or changes in consistency

Immune system impact
Chronic stress weakens your immune system
A weakened immune system can allow the natural bacteria and yeast in your vagina to become imbalanced
This can lead to:
Yeast infections - causing thick, white, clumpy discharge with itching
Bacterial vaginosis - causing thin, gray discharge with a fishy odor

Cycle irregularity
Stress can delay ovulation or cause you to skip it entirely
When your cycle shifts, your discharge patterns shift too
You might not see the usual ovulation discharge you expect mid-cycle

Types of stress that can affect discharge
Work or financial pressure
Relationship difficulties
Major life changes (moving, job changes, loss)
Sleep deprivation
Over-exercising
Illness or chronic health conditions

What you can do
Track your symptoms - Noting stress levels alongside discharge changes helps you see the connection
Manage stress - Exercise, sleep, meditation, and social support all help regulate cortisol
Maintain vaginal health - Wear breathable underwear, avoid scented products, and eat a balanced diet
See a doctor if needed - If stress-related discharge changes persist or are accompanied by itching, odor, or pain

Femora's daily mood and symptom logging helps you track how stress and emotional changes correlate with your cycle patterns.

Question 15

How can I maintain healthy vaginal hygiene?

Femora · Accepted Answer

Good vaginal hygiene is simpler than most people think. The key principle: your vagina is self-cleaning - your job is to support that process, not interfere with it.

The basics

Do: Wash the vulva gently
Clean the external area (vulva) with warm water daily
If you use soap, choose a mild, unscented, pH-balanced wash
Gently wash the folds of the labia
Never wash inside the vagina - it cleans itself through discharge

Don't: Douche
Douching disrupts the natural balance of bacteria
It washes away the good bacteria (lactobacilli) that protect against infections
Studies consistently show douching increases the risk of infections, not decreases it

Daily habits

Underwear
Wear breathable, cotton underwear - cotton allows air circulation
Change underwear daily
Avoid wearing wet or damp underwear (after swimming or exercise)
Going commando at night can help with air circulation

Clothing
Avoid tight-fitting pants or leggings for prolonged periods
Change out of sweaty workout clothes promptly
Wear loose-fitting clothes when possible, especially in hot weather

Wiping
Always wipe front to back after using the toilet
This prevents bacteria from the rectal area from entering the vagina

Menstrual products
Change pads every 4–6 hours
Change tampons every 4–8 hours (never leave one in longer than 8 hours)
Clean menstrual cups according to manufacturer instructions
Wash your hands before and after changing products

What to avoid
Scented products - No scented soaps, sprays, wipes, or deodorants near the vagina. These disrupt pH and can cause irritation
Harsh cleansers - Regular soap can be too alkaline for the vaginal area
Scented tampons or pads - Opt for unscented varieties
Sitting in wet clothes - Warm, moist environments encourage yeast growth
Over-washing - Washing the vulva once daily is sufficient. More can cause dryness and irritation

Diet and lifestyle
Stay hydrated - Water supports healthy mucus production
Eat probiotics - Yogurt, kefir, and fermented foods support healthy vaginal bacteria
Limit sugar - Excess sugar can promote yeast growth
Practice safe sex - Use condoms to reduce STI risk; urinate after sex to help prevent UTIs

During your period
Maintain regular hygiene practices
Change products frequently
Shower or wash the vulva at least once daily
It's fine to shower or bathe during your period

When to see a doctor

Even with good hygiene, infections can happen. See a doctor if you notice:
Unusual discharge (color, smell, or texture changes)
Persistent itching or burning
Pain during urination or sex
Any sores, bumps, or rashes

Track your daily symptoms and cycle in Femora to stay aware of changes and keep your healthcare provider informed with accurate data.

Question 16

Is it normal to have discharge every day?

Femora · Accepted Answer

Yes - having some amount of discharge every day is completely normal for most people of reproductive age. It's a sign that your body is functioning as it should.

Why you have daily discharge

Your vagina continuously produces fluid to:
Maintain moisture in the vaginal tissues
Clean itself by flushing out old cells and bacteria
Protect against infections by maintaining an acidic pH

This process doesn't stop - it happens every day, not just during certain parts of your cycle.

How daily discharge varies

While discharge is present most days, it changes throughout your cycle:
Light days (after your period, before ovulation builds up): Minimal, thick, or sticky. You might barely notice it
Heavier days (around ovulation): More abundant, clear, and slippery. This is when you'll notice it most
Moderate days (luteal phase): Creamy, white, moderate amount

Some days you might produce more, some days less - this variation is normal.

How much is normal?
Average: 1–4 ml per day (about half to one teaspoon)
Around ovulation: Can increase to several ml
Individual variation: Some people naturally produce more than others

Factors that increase daily discharge
Hormonal birth control - Can increase or change discharge
Pregnancy - Discharge typically increases
Sexual arousal - Temporary increase in lubrication
Exercise - Can temporarily increase discharge
Diet and hydration - Staying hydrated supports healthy discharge production

When daily discharge is NOT normal

While having discharge daily is fine, certain types warrant attention:
Daily discharge that is yellow, green, or gray
Daily discharge with a strong or foul odor
Discharge that causes constant itching or irritation
A sudden significant increase from your normal baseline

Tips for comfort

If daily discharge is uncomfortable:
Wear cotton underwear for breathability
Use unscented panty liners if needed (change frequently)
Avoid scented products in the vaginal area
Keep the vulva clean and dry

Femora helps you understand what's normal for your body by tracking your daily symptoms and cycle phases over time.

Question 17

Can discharge be a sign of pregnancy?

Femora · Accepted Answer

Yes - changes in discharge can be one of the early signs of pregnancy, though it's not a reliable indicator on its own.

Early pregnancy discharge

In early pregnancy, many people notice an increase in discharge called leukorrhea. This discharge is typically:
White or milky in color
Thin and mild-smelling (or odorless)
More abundant than usual

This increase begins soon after conception and can be one of the earliest changes you notice - sometimes even before a missed period.

Why discharge increases in pregnancy
Rising estrogen levels - Estrogen increases dramatically in early pregnancy, stimulating more cervical mucus production
Increased blood flow - More blood flows to the pelvic area during pregnancy, increasing vaginal secretions
Protective function - The extra discharge helps protect the birth canal from infection
Mucus plug formation - The cervix begins forming a mucus plug that seals the uterus throughout pregnancy

Implantation bleeding vs. discharge

Around 10–14 days after conception, some people experience implantation bleeding:
Light spotting or brown/pink discharge
Much lighter than a period
Lasts 1–2 days
Not everyone experiences this

This can be confused with an early period, but it's typically lighter and shorter.

Discharge vs. other early pregnancy signs

Discharge alone isn't enough to confirm pregnancy. Other early signs include:
Missed period - The most telling sign
Breast tenderness - Often one of the earliest symptoms
Fatigue - Unusual tiredness
Nausea - Can start as early as 2 weeks after conception
Frequent urination - Increased blood flow to the kidneys
Mild cramping - Similar to period cramps but usually lighter

When to take a pregnancy test

If you notice increased discharge along with other symptoms:
Most accurate: Wait until the day of your expected period or after
Early testing: Some tests can detect pregnancy 6 days before your missed period, but accuracy improves closer to your expected period
Best practice: Test with your first morning urine for the highest hormone concentration

Warning signs during pregnancy

If you're pregnant or suspect you might be, see a doctor if discharge is:
Yellow, green, or gray - May indicate infection
Thick and clumpy with itching - Yeast infections are more common in pregnancy
Watery and continuous - Could indicate premature rupture of membranes (in later pregnancy)
Pink or red with cramping - Could indicate a complication

Track your cycle and symptoms with Femora to know exactly when your period is expected, making it easier to spot a missed period early.

Question 18

What causes vaginal itching and when should I see a doctor?

Femora · Accepted Answer

Vaginal or vulval itching is common and usually has a treatable cause. The key is matching the itch to its likely source rather than guessing.

Common causes
Yeast infection (thrush) - the most common cause of intense itching, usually with thick, white, cottage-cheese-like discharge and no strong odor.
Bacterial vaginosis (BV) - less itchy than yeast, but possible; the giveaway is a thin gray discharge with a fishy smell.
Irritants - scented soaps, "feminine washes," wipes, bubble baths, laundry detergent, and douching can all inflame delicate skin. This is one of the most overlooked causes.
Skin conditions - eczema, dermatitis, or lichen sclerosus can affect the vulva.
Low estrogen - during perimenopause, menopause, or breastfeeding, thinner tissue itches and feels dry.
Sexually transmitted infections - trichomoniasis, herpes, or others can cause itching.
Sweat and friction - tight or non-breathable clothing traps moisture and heat.

What to do first

Stop anything scented or harsh, switch to plain cotton underwear, and wash only the vulva with warm water. Many irritation-based itches settle within days.

When to see a doctor
Itching with abnormal discharge, odor, or burning
Itching that doesn't improve after a few days or keeps coming back
Sores, blisters, or a rash
Bleeding between periods or after sex
Itching after a new partner or possible STI exposure

Do not default to an over-the-counter antifungal unless you know it is yeast, because it won't help BV, irritation, or an STI. For the full picture, see our complete vaginal health guide.

Log itching alongside discharge and your cycle in Femora so patterns and triggers become clear.

Question 19

What does vaginal odor mean? What's normal and what's not?

Femora · Accepted Answer

Every vagina has a natural scent, and a mild smell is completely normal. It can shift slightly across your cycle, after exercise, and after sex. A problem odor is usually a clear change from your own normal, often paired with other symptoms.

What's normal
A mild, musky, or slightly tangy scent
A metallic smell around your period (blood)
A faint change after sweating or sex

These don't need treatment. The vagina is self-cleaning, and washing inside it (douching) makes odor worse, not better.

What's not normal
A strong fishy odor, especially after sex - the classic sign of bacterial vaginosis, the most common cause of odor changes.
A foul or rotten smell - can signal infection or, rarely, a forgotten tampon.
A yeasty or bread-like smell with itching and thick white discharge - points to a yeast infection.
Odor with green, yellow, or frothy discharge - can indicate trichomoniasis or another STI.

What to do

Skip scented products and douches, wear breathable cotton, and notice whether the smell comes with discharge changes, itching, or burning. A persistent fishy or foul odor is worth a clinician visit, because BV and trich need prescription treatment.

See a doctor if odor is strong and persistent, comes with abnormal discharge or itching, or follows a new partner. For how the infections differ, read yeast infection vs bacterial vaginosis.

Track odor changes with your cycle in Femora to spot when a smell is hormonal versus a sign of infection.

Question 20

What is vaginal pH and why does it matter?

Femora · Accepted Answer

Vaginal pH is a measure of how acidic the vagina is. A healthy vagina is slightly acidic, with a pH of about 3.8 to 4.5. That acidity is created by protective lactobacilli bacteria and is your first line of defense against infection.

Why acidity protects you

The acidic environment makes it hard for harmful bacteria and yeast to overgrow. When pH stays in the healthy range, the ecosystem stays balanced. When it rises above about 4.5, protective bacteria struggle and infection-causing organisms can take over.

What raises vaginal pH
Bacterial vaginosis - both a cause and a result of a higher pH
Periods - menstrual blood is less acidic, so pH rises during your period
Semen - alkaline, so pH can shift after unprotected sex
Douching and harsh washes - strip acidity and protective bacteria
Low estrogen - in menopause or breastfeeding, pH tends to rise

What it means in practice

A higher-than-normal pH is closely linked to BV, which is why at-home "vaginal pH test strips" exist. But a strip only tells you pH is off, not why, and a normal pH doesn't rule out a yeast infection (yeast can occur at normal pH). Treat a strip as a clue, not a diagnosis.

The best way to protect healthy pH is to leave the vagina alone: no douching, no scented products, and wash only the vulva with water. The microbiome does the rest. For the science, see our vaginal microbiome guide.

Femora lets you log symptoms across your cycle so you can see when changes line up with your period (when pH naturally rises) versus something worth checking.

Question 21

Yeast infection vs bacterial vaginosis: how do I tell the difference?

Femora · Accepted Answer

Yeast infections and bacterial vaginosis (BV) are the two most common vaginal infections, and they're easy to confuse. Telling them apart matters, because the treatments are completely different and using the wrong one delays relief.

The quick tell
Yeast itches. BV smells.

Yeast infection
Cause: overgrowth of the fungus Candida
Discharge: thick, white, cottage-cheese-like
Smell: usually none
Main symptom: intense itching, burning, redness, swelling
Treatment: antifungal (cream, pessary, or tablet), often available over the counter

Bacterial vaginosis (BV)
Cause: an imbalance where protective lactobacilli drop and other bacteria overgrow
Discharge: thin, white or gray
Smell: strong fishy odor, often worse after sex
Main symptom: the odor; itching is usually mild or absent
Treatment: prescription antibiotics (metronidazole or clindamycin)

Why it's worth confirming

Over-the-counter antifungals only treat yeast. If you actually have BV and use one, your symptoms won't improve. The two can also occur together, and the symptoms overlap, so when you're unsure, get tested rather than guessing.

When to see a doctor
You're not sure which one it is
Symptoms keep coming back
It's your first ever infection
You're pregnant, or have pain, fever, or abnormal bleeding

For everyday context and the 2026 update on treating recurrent BV, see our complete vaginal health guide.

Log discharge type and odor in Femora so you and your clinician can see the pattern at a glance.

Question 22

How does diet affect vaginal health?

Femora · Accepted Answer

Diet doesn't control vaginal health directly, but it influences the things that do: your blood sugar, your immune function, and the balance of your microbiome. The evidence is modest, so treat food as support, not a cure.

What may help
Fermented foods (yogurt with live cultures, kefir, kimchi) contain lactobacilli, the same family of protective bacteria that dominate a healthy vagina. Evidence is mixed but the foods are harmless and generally healthy.
Fiber and a varied, plant-rich diet support a healthier gut microbiome, which is linked to the vaginal microbiome.
Staying hydrated supports normal mucous membranes.
Enough healthy fats support hormone production, which affects tissue and lubrication.

What may hurt
High sugar intake can raise blood sugar, and uncontrolled blood sugar (including in diabetes) is a known risk factor for recurrent yeast infections, because Candida thrives on glucose.
Heavy alcohol can disrupt sleep and immune function.

The honest limits

No food "cleans" the vagina or fixes an active infection. If you have BV or a yeast infection, you need the right treatment, not a diet change. And probiotic supplements have mixed evidence for prevention, so they're optional rather than essential.

The bigger levers for vaginal health remain not douching, avoiding scented products, and getting infections properly treated. A balanced diet is a helpful supporting habit. For more, see our vaginal microbiome guide.

Use Femora to track recurrent infections alongside lifestyle factors so you can spot what actually correlates for you.

Question 23

What are the signs your vaginal microbiome is out of balance?

Femora · Accepted Answer

A healthy vaginal microbiome is dominated by protective lactobacilli that keep the environment acidic and resistant to infection. When that balance tips, it's called dysbiosis, and your body usually signals it.

Common signs
A change in discharge - more, thinner, or gray rather than your usual clear or white
A new or stronger odor, especially a fishy smell
Itching, burning, or irritation
Recurrent infections - BV or yeast that keep coming back
Discomfort during sex or urination

The single most reliable signal is a change from your own normal, which is why knowing your baseline matters so much.

What tips the balance
Douching and scented washes - strip protective bacteria
Antibiotics - kill good bacteria along with bad
Hormonal shifts - periods, pregnancy, perimenopause, menopause
Unprotected sex with a new partner - semen is alkaline and can shift the environment
Smoking and uncontrolled blood sugar

What helps

Stop douching and scented products, wash only the vulva with water, and treat infections properly when they appear. Some people use probiotics or, under medical guidance, boric acid for recurrent BV, but evidence is mixed. Live biotherapeutic products (targeted lactobacillus strains) are in trials and may become a real microbiome therapy.

If you have recurrent symptoms, see a clinician rather than self-treating in circles. For the deeper science, read our vaginal microbiome guide.

Femora makes it easy to log discharge, odor, and recurring infections so dysbiosis patterns stand out over time.

Question 24

What does pink discharge mean?

Femora · Accepted Answer

Pink discharge is usually a small amount of blood mixed with normal vaginal fluid. Most causes are harmless and tied to your cycle, but the timing and other symptoms tell you whether it's worth a closer look.

Common, normal causes
Ovulation spotting - a little light pink discharge mid-cycle, around when you ovulate
Start or end of your period - light flow looks pink before it becomes red or as it tapers
Implantation spotting - light pink or brown spotting about 10 to 14 days after conception, if you're pregnant
After sex - minor friction can cause light spotting, especially if you're dry
Starting hormonal birth control - breakthrough spotting is common in the first few months

When to pay attention
Pink or bleeding between periods that is new or repeated
Bleeding after sex that keeps happening
Pink discharge with pain, fever, or a foul odor
Any bleeding after menopause - always worth a clinician visit
Pink discharge in pregnancy with cramping

What to do

Note where you are in your cycle. Mid-cycle pink discharge that lines up with ovulation is typically normal. Pink spotting that's unexplained, repeated, painful, or post-menopausal should be checked.

Use the Ovulation Calculator to see whether spotting matches your fertile window, and read when to worry about discharge for more red flags.

Track spotting and where it falls in your cycle with Femora so you can tell ovulation spotting from something unexpected.

Question 25

Why do I feel dry? What causes vaginal dryness?

Femora · Accepted Answer

Vaginal dryness happens when the tissue produces less natural moisture, usually because of lower estrogen. It's extremely common, affects people at every age, and is very treatable, so it's worth raising rather than enduring.

Common causes
Low estrogen - the biggest driver. Estrogen keeps vaginal tissue thick, elastic, and lubricated. Levels drop in perimenopause and menopause, after childbirth, while breastfeeding, and around your period.
Some birth control and other hormonal medications
Medications - certain antihistamines, antidepressants, and cold remedies are drying
Not enough arousal before sex
Harsh products - scented soaps, washes, and douching strip moisture
Medical treatments - chemotherapy, radiation, or surgery affecting hormones
Conditions like Sjogren's syndrome

What helps
Vaginal moisturizers used regularly (not just during sex)
Lubricants during sex (water- or silicone-based)
Vaginal estrogen (cream, ring, or tablet) - very effective for menopause-related dryness and prescribed by a clinician
Stopping scented products and douching
Enough arousal and foreplay

When to see a doctor
Dryness that affects daily comfort or sex
Dryness with itching, burning, or abnormal discharge
Pain during sex that persists
Bothersome menopause symptoms

Dryness is not something you have to live with. For menopause-related changes, see our perimenopause and menopause guide.

Track dryness alongside your cycle and stage in Femora to see whether it's hormonal and time conversations with your clinician.

Question 26

What causes pain during sex?

Femora · Accepted Answer

Pain during sex (called dyspareunia) is common and almost always has an identifiable, treatable cause. It's not something to push through or feel embarrassed about.

Physical causes
Vaginal dryness or low estrogen - the most common cause, especially in perimenopause, menopause, after childbirth, or while breastfeeding
Infections - yeast, BV, or STIs cause inflammation and soreness
Not enough arousal before penetration
Vaginismus - involuntary tightening of the pelvic floor muscles
Endometriosis - often causes deep pain during or after sex
Pelvic inflammatory disease or ovarian cysts
Skin conditions of the vulva, or scarring after childbirth or surgery

Emotional and relational factors

Stress, anxiety, past trauma, and relationship strain can all contribute, and they often interact with the physical causes.

What helps
Lubricant for dryness, and vaginal estrogen if it's hormonal
Treating any infection first
More foreplay and arousal
Pelvic floor physical therapy for muscle-related pain
Treating underlying conditions like endometriosis

When to see a doctor
Pain that is new, severe, or persistent
Pain with abnormal discharge, odor, or bleeding
Deep pain during sex, which can point to endometriosis
Pain that's affecting your relationship or wellbeing

Persistent pain during sex deserves evaluation. If you also have painful periods, read period pain vs endometriosis pain.

Log pain during sex with your cycle in Femora so you can show a clinician whether it tracks with hormones, your period, or infections.

Question 27

Can tight clothing affect vaginal health?

Femora · Accepted Answer

Yes, indirectly. Tight, non-breathable clothing doesn't cause infections on its own, but it creates the warm, moist environment that yeast and bacteria prefer, which can raise your risk if you're already prone to infections.

How it happens
Trapped heat and moisture - tight synthetic leggings, shapewear, and non-cotton underwear hold sweat against the skin
Less airflow - the vulva stays damp longer
Friction and irritation - very tight seams can irritate sensitive skin

Yeast in particular thrives in warm, damp conditions, which is why infections are more common after sitting in sweaty gym clothes or a wet swimsuit.

What actually matters most

The clothing nearest your skin matters more than your outer layers. Breathable cotton underwear lets moisture escape; synthetic underwear traps it.

Practical habits
Choose cotton underwear for everyday wear
Change out of damp clothing (gym kit, swimsuits) promptly
Avoid wearing tight synthetic leggings all day without breathable underwear underneath
Consider going underwear-free at night to let the area breathe
Skip thongs if you're prone to irritation or infection

You don't need to overhaul your wardrobe. If you rarely get infections, occasional tight clothing is fine. If you get recurrent yeast or BV, switching to breathable fabrics is an easy, evidence-aligned change. For more, see the best underwear for vaginal health and our hygiene guide.

Track recurrent infections in Femora to see whether they correlate with clothing or activity habits.

Question 28

Are feminine washes necessary? What gynecologists say

Femora · Accepted Answer

No. Gynecologists and major health bodies are clear: the vagina is self-cleaning, and "feminine washes," sprays, and douches are unnecessary and can do harm.

Why they're not needed

The vagina maintains its own healthy balance through protective lactobacilli and a slightly acidic pH. It cleans itself with normal discharge. There is nothing inside that needs washing out.

Why they can backfire
Scented washes and douching strip protective bacteria and disrupt pH, which raises the risk of bacterial vaginosis and irritation, the opposite of the marketing promise.
Fragrances and harsh ingredients irritate delicate vulval skin and can trigger itching and dermatitis.
Masking odor can delay diagnosing an actual infection.

What to do instead
Wash only the vulva (the outside) with warm water
If you like, use a plain, unscented, mild cleanser on the vulva only
Never wash or douche inside the vagina
Skip sprays, wipes, "intimate deodorants," and scented products

When odor or symptoms appear

A persistent odor, itching, or abnormal discharge is a sign to see a clinician, not to reach for a wash. These usually mean an infection that needs proper treatment.

The takeaway: plain water on the vulva is all the routine cleaning you need. For the full routine, see our vaginal hygiene guide.

Femora helps you track odor and discharge changes so you can tell normal from a sign that needs care, instead of masking it.

Question 29

Can swimming, gym workouts, or sweating cause vaginal infections?

Femora · Accepted Answer

Exercise, swimming, and sweating don't directly cause infections, but staying in damp clothing afterward can create conditions that make yeast infections more likely. The activity isn't the problem; the wet kit afterward is.

Why damp clothing matters

Yeast thrives in warm, moist environments. Sitting in a sweaty gym outfit or a wet swimsuit traps heat and moisture against the skin, which can let Candida overgrow if you're prone to it.

Swimming specifics
Chlorine can irritate sensitive skin in some people but doesn't usually cause infection
The bigger risk is lingering in a wet swimsuit afterward
Hot tubs can occasionally irritate the area

Sweating and workouts

Intense exercise itself is good for you and supports overall health. The risk is only about what you do afterward and what you wear.

How to prevent it
Change out of wet or sweaty clothing promptly after swimming or the gym
Wear breathable cotton underwear day to day
Shower and dry the area gently after heavy sweating
Avoid scented products and douching, which raise risk more than exercise does
Don't sit around in damp activewear

If you get recurrent yeast infections despite these habits, see a clinician, since something else may be driving them. For more, read how to prevent recurring yeast infections.

Track infections alongside your activity and habits in Femora to spot what actually triggers them for you.

Question 30

How can I prevent recurring yeast infections?

Femora · Accepted Answer

Recurrent yeast infections (four or more in a year) are frustrating but manageable. Prevention combines daily habits, treating triggers, and sometimes a longer treatment plan from your clinician.

Daily habits that help
Wear breathable cotton underwear and change out of damp clothing promptly
Skip douching and scented products, which disrupt your natural balance
Wipe front to back
Avoid staying in wet swimsuits or sweaty gym clothes
Don't overuse antibiotics, which wipe out protective bacteria (yeast often follows a course)

Address the triggers
Blood sugar: uncontrolled blood sugar and diabetes are a major driver, because yeast feeds on glucose. Managing it can dramatically cut recurrences.
Hormones: infections may cluster at certain cycle points or with some birth control
Antibiotics: ask whether a preventive plan is appropriate if you need them often

When to see a doctor

If you get four or more infections a year, see a clinician rather than repeatedly self-treating. They can:
Confirm it's actually yeast (recurrent BV or other issues are often mistaken for it)
Prescribe a longer or maintenance antifungal course
Check for underlying causes like diabetes

What the evidence says about probiotics

Probiotics and dietary changes have mixed evidence for prevention. They're low-risk to try but shouldn't replace proper treatment or a medical workup.

Confirming the diagnosis is the single most important step, because treating the wrong thing keeps the cycle going. See yeast infection vs bacterial vaginosis.

Use Femora to log each infection with your cycle and possible triggers so patterns become obvious.

Question 31

UTI vs vaginal infection: what's the difference?

Femora · Accepted Answer

UTIs and vaginal infections are easy to confuse because both affect the same area, but they involve different parts of the body and need different treatment.

Urinary tract infection (UTI)

A UTI affects the urinary system (bladder and urethra), not the vagina.
Main symptoms: burning when you urinate, needing to pee often and urgently, cloudy or strong-smelling urine, lower-belly or back discomfort
No vaginal discharge as a primary symptom
Treatment: antibiotics

Vaginal infection (yeast or BV)

These affect the vagina itself.
Yeast: thick white discharge and intense itching, no strong odor
BV: thin gray discharge with a fishy odor, little itching
Treatment: antifungal (yeast) or prescription antibiotics (BV)

The quick distinction
Burning when you pee, frequent urge = think UTI
Itching, abnormal discharge, or odor = think vaginal infection

There is overlap: vaginal infections can sometimes cause burning, and you can have both at once, which is why testing helps when you're unsure.

When to see a doctor
UTI symptoms - get treated promptly; untreated UTIs can spread to the kidneys
Blood in urine, fever, or back pain - more urgent
Recurrent UTIs or vaginal infections
Symptoms during pregnancy

If you're not sure which you have, a clinician can test quickly. For vaginal infections specifically, see our complete vaginal health guide.

Track urinary and vaginal symptoms separately in Femora so you can describe them accurately to a clinician.

Question 32

Can antibiotics affect vaginal health?

Femora · Accepted Answer

Yes. Antibiotics treat harmful bacteria, but they can't tell the difference between bad bacteria and the protective lactobacilli that keep your vagina healthy. That collateral damage is why yeast infections often follow a course of antibiotics.

Why it happens
Antibiotics reduce protective bacteria, lowering your natural defenses
With lactobacilli depleted, yeast (Candida) can overgrow, causing itching and thick white discharge
The balance can also shift toward bacterial vaginosis in some people

This doesn't happen to everyone, and it doesn't mean you should avoid antibiotics when you genuinely need them. It just means it's worth knowing the risk.

How to reduce the risk
Only take antibiotics when truly needed and finish the prescribed course
Some people use probiotics or yogurt with live cultures during and after a course, though evidence is mixed
Watch for early symptoms so you can treat a yeast infection promptly
If you're very prone, ask your clinician whether a preventive antifungal during antibiotic courses makes sense

When to see a doctor
A yeast infection that develops during or after antibiotics (treatable with an antifungal)
Symptoms that don't clear or keep returning
Uncertainty about whether it's yeast or BV, since the treatments differ

Most post-antibiotic yeast infections are straightforward to treat. The microbiome usually recovers on its own over time. For prevention strategies, see how to prevent recurring yeast infections.

Log antibiotic courses and any symptoms that follow in Femora to see whether infections cluster around them.

Question 33

What underwear is best for vaginal health?

Femora · Accepted Answer

The best underwear for vaginal health is breathable, moisture-wicking, and not too tight - which in practice means cotton. What sits closest to your skin matters more than any other clothing choice.

Why cotton wins
Breathable - lets air circulate and moisture escape
Absorbent - pulls dampness away from the skin
This keeps the area drier, which makes it less hospitable to yeast and bacteria

Synthetic fabrics like nylon and polyester trap heat and moisture, creating the warm, damp conditions infections prefer.

Practical guidance
Choose cotton (or a cotton crotch panel) for everyday wear
Change daily, and after heavy sweating or swimming
Avoid tight, non-breathable styles all day
Thongs are fine for many people but can transfer bacteria or irritate if you're prone to infections
Consider going underwear-free at night to let the area breathe
Wash underwear in fragrance-free detergent; skip fabric softeners if you're sensitive

What matters more than the perfect pair

Underwear is one helpful factor, but it's not the biggest. Not douching, avoiding scented products, changing out of damp clothing, and treating infections properly all matter more. If you rarely get infections, you have flexibility. If you get recurrent yeast or BV, switching to cotton is an easy, evidence-aligned change.

For the bigger picture, see our vaginal hygiene guide and can tight clothing affect vaginal health.

Track recurrent infections in Femora to see whether fabric and clothing changes actually help you.

Question 34

Can you get pregnant on your period?

Femora · Accepted Answer

Yes, you can get pregnant from sex during your period. It's less likely than at other times, but a period is not a guaranteed safe window.

Why it's possible

Two facts combine to make it happen:
Sperm survive up to 5 days inside the reproductive tract.
Ovulation timing varies, and some people ovulate early.

So sperm from sex near the end of your period can still be alive several days later when an egg is released. The closer your bleeding is to an early ovulation, the higher the chance.

Who is most at risk
Short cycles. If your cycle is around 21 to 24 days, you ovulate earlier, sometimes just a few days after your period ends. Sperm from period sex can easily overlap with that.
Long periods. Bleeding for 7 days or more leaves less gap before ovulation.
Irregular cycles, where ovulation timing is hard to predict.

A common mix-up

Some bleeding isn't a period. Light bleeding around ovulation (spotting) or breakthrough bleeding can be mistaken for a period, and sex during that bleeding lands squarely in the fertile window. If you're tracking to avoid or achieve pregnancy, knowing whether bleeding is a true period matters.

What this means for you
Trying to avoid pregnancy? Don't rely on your period as protection, especially with short or irregular cycles. Use contraception.
Trying to conceive? Period sex rarely lands in the fertile window, so focus on the days leading up to and including ovulation instead.

Know your own pattern: map your cycle with the Menstrual Cycle Calculator, find your fertile days with the Fertile Window Calculator and Ovulation Calculator, and learn the body's signs in our guide to ovulation symptoms.

Femora predicts your fertile window from your own logged cycles, so you can see exactly when pregnancy is and isn't likely.

Question 35

What is a normal period?

Femora · Accepted Answer

A "normal" period covers a wide range, and your normal is what matters most. As a guide, most healthy periods fall within these ranges.

Typical ranges
Cycle length: 21 to 35 days from the first day of one period to the first day of the next
Period length: 2 to 7 days of bleeding
Blood loss: about 5 to 80 ml total (roughly 2 to 6 soaked regular pads or tampons a day at most)
Color: bright to dark red, sometimes brown at the start or end

What's normal for you

Periods vary from person to person and can shift with age, stress, and life stage. The most useful signal is consistency and change from your own baseline, not hitting an exact textbook number.

When to check with a doctor
Cycles consistently shorter than 21 or longer than 35 days
Bleeding longer than 7 days or very heavy (clots, flooding)
No periods for 3 or more months (and not pregnant)
Severe pain, or bleeding between periods

Track a few cycles with the Menstrual Cycle Calculator to learn your baseline, and read more on what your cycle reveals.

Femora logs your length, duration, and flow so you can see your own normal at a glance.

Question 36

How long does a period last?

Femora · Accepted Answer

Most periods last 2 to 7 days, with the average around 5 days. Bleeding is usually heaviest in the first 2 days and tapers off after that.

What's typical
Day 1 to 2: heaviest flow, bright red
Day 3 onward: lighter, sometimes darker or brown as it ends
Total: 2 to 7 days is the normal range

Period length can vary cycle to cycle and changes naturally with age, hormonal birth control, and life stage.

When length is worth checking
Longer than 7 days regularly (prolonged bleeding)
Shorter than 2 days, especially if it's a new change
Very irregular length from cycle to cycle
Bleeding that's very heavy or comes with severe pain

Short or long bleeding can reflect hormones, birth control, thyroid issues, fibroids, or PCOS/PMOS. A new, lasting change from your usual is the thing to note.

Track your period length over a few cycles with the Menstrual Cycle Calculator.

Femora records exactly how long each period lasts so changes stand out over time.

Question 37

How much blood do you lose during your period?

Femora · Accepted Answer

Most people lose about 5 to 80 ml of blood over a whole period, which is roughly 2 to 6 tablespoons. It often looks like more because it mixes with uterine lining and fluid.

Putting it in perspective
A soaked regular tampon or pad holds about 5 ml
A fully soaked super tampon or pad holds about 10 ml
Losing more than about 80 ml per period is considered heavy

Signs your flow may be heavy
Soaking through a pad or tampon every 1 to 2 hours
Needing to change protection overnight
Passing clots larger than a 2 pound coin (about 2.5 cm)
Flooding through to clothes or bedding
Symptoms of anemia like tiredness, breathlessness, or paleness

Heavy bleeding is common and treatable, and it can point to fibroids, hormonal imbalance, or other causes worth checking.

If your flow feels heavy, read what is a heavy period and track it in Femora.

Log your flow intensity daily in Femora to estimate whether your loss is in the typical range.

Question 38

What is a heavy period (menorrhagia)?

Femora · Accepted Answer

A heavy period (menorrhagia) means losing more blood than usual, enough to disrupt your daily life. It's common, affects about 1 in 3 women at some point, and is treatable.

Signs of a heavy period
Soaking through a pad or tampon every 1 to 2 hours
Needing double protection (pad plus tampon)
Changing protection overnight
Passing large clots (bigger than about 2.5 cm)
Bleeding longer than 7 days
Signs of anemia: fatigue, breathlessness, pale skin

Common causes
Hormonal imbalance (including around perimenopause)
Fibroids or polyps
Adenomyosis or endometriosis
PCOS/PMOS or thyroid problems
Bleeding disorders or some medications and IUDs (copper)

When to see a doctor

See a clinician if bleeding is heavy enough to affect your life, you're passing large clots, or you have anemia symptoms. Effective treatments range from hormonal options to treating the underlying cause.

Track flow and clots in Femora, and learn the difference between normal and concerning period pain.

Femora's flow logging gives your clinician concrete data instead of guesswork.

Question 39

Why is my period so heavy?

Femora · Accepted Answer

Heavy periods are common and usually have an identifiable, treatable cause. A sudden change to heavier bleeding is worth investigating.

Common reasons
Hormonal imbalance - too much estrogen relative to progesterone thickens the lining
Perimenopause - hormone swings often cause heavier, irregular periods
Fibroids and polyps - benign growths in the uterus
Adenomyosis - uterine lining tissue growing into the muscle wall
PCOS/PMOS - irregular ovulation can lead to heavy bleeds
Thyroid problems or bleeding disorders
Copper IUD - can increase flow
Stopping hormonal birth control

When to see a doctor
Bleeding that soaks a pad or tampon every 1 to 2 hours
Large clots or bleeding longer than 7 days
Fatigue, breathlessness, or paleness (possible anemia)
A sudden change to much heavier periods

Heavy bleeding is treatable, often with hormonal options or by addressing the cause, so it's worth raising rather than enduring.

See what is a heavy period for the full picture and track your flow with Femora.

Logging flow and clots in Femora helps you and your doctor pinpoint what changed.

Question 40

What causes blood clots during your period?

Femora · Accepted Answer

Small period clots are normal, especially on your heaviest days. They form when blood pools faster than your body's anti-clotting agents can keep up.

What's normal
Small clots (smaller than a 10p coin or about 2 cm), bright or dark red
More common on heavy-flow days and overnight
Often darker first thing in the morning

When clots are worth checking
Large clots (bigger than about 2.5 cm)
Clots with very heavy bleeding (soaking a pad or tampon every 1 to 2 hours)
Clots plus anemia symptoms like fatigue or breathlessness
A new or worsening pattern

Large or frequent clots often go with heavy periods, which can be caused by fibroids, hormonal imbalance, adenomyosis, or PCOS/PMOS.

What to do

Note clot size (compare to a coin) and how often you change protection. Bring that to a clinician if clots are large or come with heavy flow.

Learn more in what is a heavy period, and track clots and flow in Femora.

Femora lets you log clots and flow so patterns and changes are easy to spot.

Question 41

Why is my period blood brown or dark?

Femora · Accepted Answer

Brown or dark period blood is almost always normal. The color simply means the blood is older and has had time to oxidize before leaving the body.

When brown blood is normal
At the start of your period, as flow is just beginning
At the end of your period, as flow slows and older blood clears
Light spotting between periods or around ovulation
First thing in the morning, when blood has pooled overnight

When to pay attention
Brown discharge with a foul or fishy odor (possible infection)
Itching, burning, or pain alongside it
Brown spotting that is frequent or unexplained between periods
Any bleeding after menopause
Brown spotting in pregnancy with cramping

What to do

Note when in your cycle it happens. Brown at the very start or end of your period is expected. Unexplained, smelly, or post-menopausal brown discharge should be checked.

For color specifics, see what does period blood color mean, and track spotting with Femora.

Femora helps you log spotting and color so you can tell routine from unusual.

Question 42

What does period blood color mean?

Femora · Accepted Answer

Period blood changes color through your period, and most shades are completely normal. Color mainly reflects how old the blood is and how fast it's flowing.

What the colors usually mean
Bright red: fresh, steady flow, often mid-period
Dark red: slightly older blood, common on heavier days or waking up
Brown or black: older, oxidized blood, typical at the start or end
Pink: blood mixed with cervical fluid, light flow, or ovulation spotting
Orange or gray: can signal infection, especially with odor or itching, worth a check

When color is worth attention
Gray discharge, or orange with a bad smell (possible infection)
Very pale, watery bleeding that's a new change
Any bleeding after menopause
Unusual color with pain, odor, or itching

The bottom line

Red, dark red, brown, and pink across a period are all usually normal. Gray or foul-smelling discharge is the main color flag for infection.

See why is my period blood brown and what does pink discharge mean for specifics.

Track flow color and symptoms in Femora to tell normal variation from a sign worth checking.

Question 43

Why is my period shorter than usual?

Femora · Accepted Answer

A shorter or lighter period than usual is often harmless, but a lasting change is worth understanding.

Common reasons
Hormonal birth control - the pill, implant, hormonal IUD, and injection often shorten or lighten periods
Stress - can shorten or delay cycles
Weight or exercise changes - significant shifts affect hormones
Perimenopause - periods often become shorter, lighter, or irregular
Thyroid issues or PCOS/PMOS
Pregnancy - light bleeding can be mistaken for a short period (including implantation spotting)
Age - cycles naturally change over the years

When to check with a doctor
A sudden, lasting change in length
Very light spotting instead of a period, especially if you could be pregnant
Periods that become very irregular
Other symptoms like pain, missed periods, or signs of pregnancy

A single short period is rarely a concern. A consistent new pattern is what's worth raising.

Track your period length over several cycles with the Menstrual Cycle Calculator, and if you could be pregnant, read can discharge be a sign of pregnancy.

Femora tracks period length so you can see whether a short period is a one-off or a trend.

Question 44

What causes irregular periods?

Femora · Accepted Answer

Irregular periods mean the timing, length, or flow varies a lot from cycle to cycle. Occasional irregularity is common; a persistent pattern is worth investigating.

Common causes
Puberty and perimenopause - cycles are naturally irregular at both ends of reproductive life
PCOS/PMOS - one of the most common causes of irregular or missed periods
Thyroid problems - both over- and underactive thyroid
Stress and poor sleep
Significant weight change or intense exercise
Hormonal birth control - starting, stopping, or switching
High prolactin or other hormonal imbalances
Perimenopause

When to see a doctor
Cycles consistently shorter than 21 or longer than 35 days
Missed periods (3 or more in a row) when not pregnant
Very heavy or prolonged bleeding
Irregularity plus other symptoms (acne, excess hair, weight changes) that may point to PCOS/PMOS

What helps

Identifying the cause is the key. Tracking your cycles makes the pattern visible and gives your clinician something concrete to work with.

Learn the basics in what is PCOS, and map your cycles with the Menstrual Cycle Calculator.

Femora reveals irregular patterns over time so you can act on them earlier.

Question 45

Why am I bleeding between periods?

Femora · Accepted Answer

Light bleeding or spotting between periods (intermenstrual bleeding) is common and often harmless, but some causes need checking.

Common, usually harmless causes
Ovulation spotting - light bleeding mid-cycle
Starting hormonal birth control - breakthrough bleeding in the first few months
Missed birth control pills
Implantation - light spotting in early pregnancy

Causes worth checking
Infections including STIs (chlamydia) or vaginal infections
Polyps or fibroids
Hormonal imbalance, PCOS/PMOS, or thyroid issues
Perimenopause
Rarely, cervical or uterine changes

When to see a doctor
Bleeding between periods that is new, repeated, or unexplained
Bleeding after sex
Bleeding with pain, fever, or unusual discharge
Any bleeding after menopause (always get this checked)

Spotting that lines up with ovulation or the start of birth control is usually fine. New, repeated, or post-menopausal bleeding should always be evaluated.

Track spotting against your cycle with the Ovulation Calculator to see if it matches ovulation.

Femora lets you log spotting and where it falls in your cycle, so you can tell ovulation spotting from something unexpected.

Question 46

What is spotting and is it normal?

Femora · Accepted Answer

Spotting is light bleeding outside your normal period - usually just a few drops or a pink or brown tinge on underwear or when you wipe. It's common and often normal.

Common, normal causes
Ovulation spotting - around the middle of your cycle
Starting hormonal birth control - breakthrough bleeding for the first few months
Implantation - light spotting in early pregnancy, around 10 to 14 days after conception
Start or end of your period
After sex - minor friction, especially if dry

When spotting is worth checking
New, repeated, or unexplained spotting between periods
Bleeding after sex that keeps happening
Spotting with pain, odor, or unusual discharge
Any spotting after menopause
Spotting in pregnancy with cramping

What to do

Note the timing and color. Mid-cycle spotting that lines up with ovulation, or breakthrough bleeding when you start birth control, is usually normal. Anything new, repeated, or post-menopausal should be checked.

See why am I bleeding between periods and use the Ovulation Calculator to check timing.

Femora makes it easy to log spotting and see whether it matches ovulation or something else.

Question 47

At what age do periods start?

Femora · Accepted Answer

Most people get their first period (called menarche) between ages 10 and 15, with the average around 12. There's a wide normal range, and timing is influenced by genetics, weight, and overall health.

What to expect
First periods are often irregular for the first 1 to 2 years while the cycle settles
Cycles may be longer, shorter, or skipped at first
Flow and length can vary a lot early on

This is normal as the hormonal system matures.

Signs a period may be coming soon
Breast development (usually starts about 2 years before)
Vaginal discharge appearing in the months before
A growth spurt

When to check with a doctor
No period by age 15, or no signs of puberty by 13
No period within 3 years of breast development
Periods that were regular then stop
Very heavy, very painful, or extremely irregular periods that disrupt life

Early tracking helps a teen learn their pattern as cycles settle.

Map cycles with the Menstrual Cycle Calculator and read about the four cycle phases.

Femora helps track those first irregular cycles so a normal pattern becomes clear over time.

Question 48

What is a normal menstrual cycle length?

Femora · Accepted Answer

A menstrual cycle is counted from the first day of one period to the first day of the next. A normal cycle length is 21 to 35 days, with the average around 28.

What's typical
21 to 35 days is the healthy adult range
Teens often have longer, more variable cycles for the first couple of years
Cycles can shift over time with age, stress, and life stage
A small variation of a few days month to month is normal

What's worth checking
Cycles consistently shorter than 21 days
Cycles consistently longer than 35 days
Wide swings in length from cycle to cycle
Missed periods (3 or more) when not pregnant

These can reflect PCOS/PMOS, thyroid issues, perimenopause, stress, or other hormonal factors.

Why it matters

Your cycle length sets the timing of ovulation and your fertile window, so knowing it helps with both conceiving and avoiding pregnancy.

Find your average with the Menstrual Cycle Calculator, and see the four phases.

Femora calculates your average cycle length from your logs and sharpens its predictions over time.

Question 49

Why did my period stop suddenly?

Femora · Accepted Answer

Periods stopping (called amenorrhea when you miss 3 or more in a row) has many possible causes. Pregnancy is the most common, but it's far from the only one.

Common causes
Pregnancy - the first thing to rule out if you're sexually active
Breastfeeding
Significant weight loss or being underweight
Excessive exercise (common in athletes)
Severe or ongoing stress
PCOS/PMOS
Thyroid problems or high prolactin
Perimenopause and menopause
Hormonal birth control - some methods stop periods (this is normal and safe)
Coming off the pill - it can take a few months to restart

When to see a doctor
No period for 3 or more months and not pregnant
Missed periods with other symptoms (headaches, vision changes, milky nipple discharge, excess hair)
Periods that stop after being regular

Missing periods is often reversible once the cause is addressed, but it's worth investigating because long-term absence can affect bone and heart health.

Take a pregnancy test first if relevant, then track with the Menstrual Cycle Calculator. See also why is my period late.

Femora flags missed periods early so you can act sooner.

Question 50

What causes period cramps?

Femora · Accepted Answer

Period cramps (dysmenorrhea) are caused by your uterus contracting to shed its lining. The contractions are driven by hormone-like chemicals called prostaglandins - higher levels mean stronger cramps.

Two types
Primary dysmenorrhea: ordinary period cramps with no underlying disease. Common, often eases with age and after childbirth.
Secondary dysmenorrhea: cramps caused by a condition like endometriosis, adenomyosis, fibroids, or PID. These tend to be more severe or worsen over time.

Typical pattern
Cramping in the lower abdomen, sometimes the back and thighs
Starts just before or as your period begins
Worst in the first 1 to 2 days
May come with bloating, loose stools, headache, or fatigue

When to see a doctor
Pain that doesn't ease with NSAIDs (ibuprofen, naproxen)
Pain that gets worse over time or is severe enough to disrupt life
Pain during sex or bowel movements
Cramps with heavy bleeding or that start later in life

Worsening or NSAID-resistant pain can point to endometriosis.

See how to relieve period cramps and period pain vs endometriosis pain.

Track cramp severity with your cycle in Femora to spot whether pain is steady or worsening.

Question 51

How can I relieve period cramps?

Femora · Accepted Answer

Most period cramps respond well to a few simple, evidence-backed measures. The key is starting early, ideally at the first sign of cramps.

What works best
NSAIDs (ibuprofen, naproxen) - the most effective option, because they reduce the prostaglandins that cause cramps. Take at the first twinge, with food.
Heat - a hot water bottle or heat patch on your lower abdomen is genuinely effective
Gentle exercise - walking, stretching, or yoga can ease pain
Rest and sleep

Also worth trying
Staying hydrated and limiting salt to reduce bloating
Magnesium and some other supplements (modest evidence)
A TENS machine for some people
Hormonal birth control can reduce cramps over the longer term

What to be careful with

NSAIDs aren't for everyone (for example, with stomach ulcers or certain conditions), so check if unsure.

When to see a doctor
Cramps that don't respond to NSAIDs and heat
Pain that's severe, worsening, or disrupts daily life
Pain with heavy bleeding, pain during sex, or bowel symptoms

Persistent or escalating pain can signal endometriosis and deserves evaluation.

See what causes period cramps and track pain in Femora.

Femora helps you log what relief methods work best for your cramps over time.

Question 52

When are period cramps a sign of something serious?

Femora · Accepted Answer

Ordinary period cramps are common and not dangerous. But certain patterns suggest a condition that needs evaluation, most often endometriosis, adenomyosis, fibroids, or pelvic inflammatory disease.

Red flags worth checking
Pain that doesn't ease with NSAIDs (ibuprofen, naproxen)
Pain that is getting worse over time rather than staying steady
Cramps severe enough to disrupt work, school, or daily life
Pain during or after sex
Pain with bowel movements or urination, especially during your period
Cramps with very heavy bleeding or large clots
Cramping between periods or pain that lasts beyond your period
New, severe pain that started later in adulthood

Why it matters

Endometriosis affects roughly 1 in 10 women and takes years to diagnose on average, partly because severe period pain gets normalized. Getting evaluated earlier can change that.

What to do

Track when the pain happens, how severe it is, and whether NSAIDs help. That record helps a clinician distinguish ordinary cramps from a condition.

Read period pain vs endometriosis pain and is severe period pain normal.

Femora lets you log pain severity over months so worsening patterns are easy to show a doctor.

Question 53

What is PMS?

Femora · Accepted Answer

PMS (premenstrual syndrome) is the cluster of physical and emotional symptoms many people get in the 1 to 2 weeks before their period, during the luteal phase. Symptoms ease once your period starts.

Common symptoms

Physical:
Bloating and water retention
Breast tenderness
Headaches
Fatigue
Cramping, acne, food cravings

Emotional:
Mood swings, irritability
Anxiety or low mood
Trouble concentrating
Changes in sleep

Why it happens

PMS is linked to the natural hormone shifts after ovulation, especially the rise and fall of progesterone and estrogen, and how they interact with brain chemicals like serotonin.

What helps
Regular exercise and good sleep
Reducing salt, caffeine, and alcohol
Stress management
Some find NSAIDs, calcium/magnesium, or hormonal birth control helpful
Tracking to anticipate symptoms

When to see a doctor

If symptoms are severe enough to disrupt your life or relationships, you may have PMDD (a more severe form), which is treatable.

Compare in PMS vs PMDD and read our PMS vs PMDD guide.

Femora helps you track PMS symptoms across cycles so you can predict and manage them.

Question 54

What are the symptoms of PMS?

Femora · Accepted Answer

PMS symptoms appear in the luteal phase (the 1 to 2 weeks before your period) and ease once bleeding starts. Most people have a few, not all, and the pattern is usually consistent month to month.

Physical symptoms
Bloating and water retention
Breast tenderness or swelling
Headaches or migraines
Fatigue and low energy
Cramping and lower back ache
Acne breakouts
Food cravings or appetite changes
Constipation or diarrhea

Emotional and mental symptoms
Mood swings and irritability
Anxiety or feeling on edge
Low mood or tearfulness
Trouble concentrating ("brain fog")
Changes in sleep (too much or too little)
Lower libido

The key feature

What makes it PMS is the timing: symptoms come before your period and resolve once it starts. If they're constant, something else may be going on.

When to see a doctor

If symptoms are severe and disrupt daily life or relationships, especially the emotional ones, you may have PMDD, which is treatable.

See what is PMDD and track symptoms in Femora.

Femora's symptom logging confirms whether your symptoms truly follow your cycle, the hallmark of PMS.

Question 55

What is PMDD?

Femora · Accepted Answer

PMDD (premenstrual dysphoric disorder) is a severe form of PMS with intense emotional and physical symptoms that significantly disrupt daily life, work, and relationships. It affects an estimated 3 to 8% of women.

How it differs from PMS

PMDD shares PMS's timing (symptoms in the luteal phase, easing when the period starts) but the emotional symptoms are much more severe - severe enough to interfere with functioning.

Key symptoms
Severe mood swings, anger, or irritability
Marked depression, hopelessness, or anxiety
Feeling out of control or overwhelmed
Loss of interest in usual activities
Difficulty concentrating, fatigue, sleep and appetite changes
Physical PMS symptoms (bloating, breast tenderness, cramps)

Why it happens

PMDD is thought to involve an abnormal sensitivity to normal hormone changes after ovulation, affecting serotonin and mood regulation. It is a recognized medical condition, not "bad PMS" to push through.

Treatment

It's treatable. Options include SSRIs (often taken just in the luteal phase), hormonal approaches like certain birth control, lifestyle measures, and CBT.

When to see a doctor

If premenstrual symptoms disrupt your life or relationships, or you have thoughts of self-harm, seek help.

Read our PMS vs PMDD guide and track symptoms in Femora.

Tracking symptoms across cycles in Femora helps confirm the cyclical pattern that distinguishes PMDD.

Question 56

PMS vs PMDD: what's the difference?

Femora · Accepted Answer

PMS and PMDD share the same timing - symptoms before your period that ease once it starts - but they differ sharply in severity and impact.

PMS
Common (most people who menstruate get some symptoms)
Mild to moderate physical and emotional symptoms
Manageable with lifestyle measures
Doesn't usually disrupt your ability to function

PMDD
Less common (about 3 to 8% of women)
Severe, mainly emotional symptoms: intense mood swings, depression, anxiety, anger, feeling out of control
Disrupts work, relationships, and daily life
A recognized medical condition needing treatment

The dividing line

It's about impact. If symptoms are bothersome but manageable, that's PMS. If they're severe enough to derail your life or relationships each month, that points to PMDD.

What to do
PMS: exercise, sleep, reduce salt/caffeine/alcohol, manage stress
PMDD: see a clinician; SSRIs, hormonal options, and CBT are effective

Tracking symptoms across at least two cycles is how clinicians confirm the cyclical pattern for either one.

Read our full PMS vs PMDD guide, and see what is PMDD.

Femora's symptom tracking shows whether symptoms are mild PMS or severe, cyclical PMDD worth discussing with a doctor.

Question 57

Why do I feel bloated before my period?

Femora · Accepted Answer

Premenstrual bloating is very common and is driven by the hormone shifts in the days before your period. It usually eases once bleeding begins.

Why it happens
Hormones: rising and falling estrogen and progesterone cause your body to retain water and salt, leading to that puffy, swollen feeling
Digestion: the same hormones can slow the gut, causing gas and constipation that add to bloating
Cravings: salty and carb-heavy premenstrual cravings increase water retention

What helps
Reduce salt in the days before your period
Stay hydrated (it actually reduces water retention)
Limit caffeine, alcohol, and carbonated drinks
Gentle exercise and movement
Fiber to ease constipation
Some find magnesium or NSAIDs helpful

When to see a doctor
Bloating that's severe, constant, or not linked to your cycle
Bloating with pain, changes in bowel habits, or weight loss
Persistent bloating that doesn't go away after your period

Cyclical bloating that comes and goes with your period is normal. Constant or severe bloating deserves a check, since persistent bloating has other causes.

Track bloating with your cycle in Femora and see what are the symptoms of PMS.

Femora confirms whether bloating follows your cycle, helping separate PMS from something else.

Question 58

Can your period cause headaches?

Femora · Accepted Answer

Yes. Many people get hormone-related headaches or menstrual migraines around their period, triggered by the natural drop in estrogen just before bleeding starts.

Why it happens

Estrogen falls sharply in the late luteal phase. For people prone to migraine, this drop is a powerful trigger. These headaches often hit 2 days before to 3 days into your period.

Menstrual migraine features
Often more intense and longer-lasting than other migraines
May come with nausea, light and sound sensitivity
Can be harder to treat than non-hormonal migraines

What helps
NSAIDs (ibuprofen, naproxen), sometimes started a couple of days before your period
Staying hydrated, regular meals, and good sleep
Triptans for migraine (prescribed)
For some, stable-estrogen birth control approaches reduce the drop (discuss with a clinician)
Tracking to anticipate and pre-empt them

When to see a doctor
Headaches that are severe, frequent, or disabling
A sudden, very severe headache (seek urgent care)
Headaches with aura plus combined hormonal contraception (raises stroke risk, needs review)
New headaches after age 50

Track headaches against your cycle in Femora to confirm the hormonal link.

Femora helps you see whether headaches cluster around your period so you can treat them proactively.

Question 59

Why do I feel nauseous during my period?

Femora · Accepted Answer

Feeling nauseous around your period is common and usually harmless. It's mostly driven by prostaglandins, the same chemicals that cause cramps.

Common causes
Prostaglandins: high levels cause stronger uterine contractions and can also affect the stomach and gut, triggering nausea and loose stools
Hormone shifts: estrogen and progesterone changes can affect digestion
Menstrual migraines: often come with nausea
Severe cramps: intense pain itself can cause nausea
PMS: nausea can be part of the broader symptom mix

What helps
NSAIDs (ibuprofen, naproxen) reduce prostaglandins and may ease both cramps and nausea
Ginger (tea or supplements) has decent evidence for nausea
Small, bland meals and staying hydrated
Rest and avoiding strong smells or greasy food

When to see a doctor
Severe or persistent nausea or vomiting each cycle
Nausea with severe pain, which can point to endometriosis or other conditions
Nausea that could be early pregnancy if your period is late or unusually light
Nausea with fever or other concerning symptoms

Mild cyclical nausea is normal; severe or worsening symptoms deserve evaluation.

See what causes period cramps, and track nausea with your cycle in Femora.

Femora lets you log nausea alongside cramps so you can see the pattern and what relieves it.

Question 60

What is the follicular phase?

Femora · Accepted Answer

The follicular phase is the first half of your menstrual cycle, from the first day of your period until ovulation. It's named for the follicles in your ovaries that mature during this time.

What happens
Day 1: your period starts (the follicular phase includes menstruation)
Rising estrogen stimulates several follicles, each holding an egg, to grow
The uterine lining begins to rebuild and thicken
Usually one dominant follicle matures, ready to release an egg at ovulation
Cervical mucus becomes clearer and more slippery as estrogen rises

How long it lasts

The follicular phase is the most variable part of the cycle, typically about 10 to 16 days. Its length is what makes cycles longer or shorter, because the second half (luteal phase) stays fairly fixed at around 14 days.

Why it matters

Because the follicular phase varies, ovulation doesn't always land on day 14. A longer follicular phase means later ovulation, which is why tracking beats counting calendar days.

How you might feel

Many people report rising energy and mood as estrogen climbs toward ovulation.

See the four cycle phases and find your likely ovulation with the Ovulation Calculator.

Femora tracks your follicular phase length so it can predict ovulation accurately for your cycle.

Question 61

What is the luteal phase?

Femora · Accepted Answer

The luteal phase is the second half of your cycle, from ovulation until your next period. It's when your body prepares for a possible pregnancy.

What happens
After ovulation, the empty follicle becomes the corpus luteum, which produces progesterone
Progesterone thickens and stabilizes the uterine lining for a potential embryo
Your basal body temperature rises slightly (a sign ovulation happened)
If no pregnancy occurs, the corpus luteum breaks down, progesterone drops, and your period begins

How long it lasts

The luteal phase is fairly consistent at about 12 to 14 days, unlike the variable follicular phase. A luteal phase shorter than about 10 days is called a short (or luteal phase) defect and can occasionally affect fertility.

How you might feel

The progesterone-dominant luteal phase is when PMS symptoms appear - bloating, breast tenderness, mood changes - especially in the final days as hormones fall.

Why it matters

Because the luteal phase length is stable, it's the anchor used to estimate ovulation from your cycle length.

See what is a short luteal phase and the four cycle phases.

Femora uses your luteal phase timing to predict your next period and fertile window.

Question 62

What is a short luteal phase?

Femora · Accepted Answer

A short luteal phase (sometimes called a luteal phase defect) is when the time between ovulation and your next period is under about 10 days. The typical luteal phase is 12 to 14 days.

Why it can matter

After ovulation, progesterone thickens the uterine lining so an embryo can implant. If the luteal phase is too short, the lining may shed before implantation can succeed, which can occasionally make conceiving harder.

Possible causes
Stress or significant weight or exercise changes
Thyroid problems or high prolactin
PCOS/PMOS and other hormonal imbalances
Perimenopause
Sometimes no clear cause

Signs you might notice
Spotting in the days before your full period
A short gap between ovulation (e.g., confirmed by a temperature rise) and your period
Difficulty conceiving alongside a short post-ovulation window

What to do

A one-off short luteal phase isn't a concern. A consistent pattern, especially with trouble conceiving, is worth discussing with a clinician, who can check hormones and underlying causes.

Tracking ovulation (via temperature or OPKs) and your period start date is how you measure your luteal phase.

Learn to confirm ovulation in how do I know when I'm ovulating, and track timing in Femora.

Femora helps you measure the gap between ovulation and your period so a short luteal phase is easy to spot.

Question 63

What is the fertile window?

Femora · Accepted Answer

The fertile window is the span of days in your cycle when sex can lead to pregnancy. It's about 6 days long: the 5 days before ovulation plus ovulation day itself.

Why it's 6 days
Sperm survive up to 5 days in the reproductive tract
An egg lives only 12 to 24 hours after ovulation

So sperm present in the days before ovulation can still fertilize the egg when it's released. Your most fertile days are the 2 to 3 days before and including ovulation.

How to find it
Estimate from cycle length using the Fertile Window Calculator and Ovulation Calculator
Watch cervical mucus - clear, slippery, egg-white texture signals peak fertility
Use ovulation predictor kits - detect the LH surge 24 to 36 hours before ovulation
Track basal body temperature - confirms ovulation after it happens

Why it matters
Trying to conceive: time sex to the fertile window, especially the days just before ovulation
Avoiding pregnancy: the fertile window is when to use protection (note that fertility-awareness methods require careful tracking and rules)

Ovulation isn't always on day 14, so the fertile window shifts with your cycle.

Read ovulation symptoms for how to pin it down.

Femora predicts your fertile window from your own cycles and sharpens as you log more.

Question 64

How do I track my menstrual cycle?

Femora · Accepted Answer

Tracking your cycle means recording a few key things each month so you can learn your pattern, predict your period and fertile window, and spot changes early.

What to record
Period start and end dates - the foundation of everything
Flow intensity - light, medium, heavy, plus any clots
Symptoms - cramps, mood, bloating, headaches, breast tenderness
Cervical mucus - dry, creamy, or clear and slippery
Optional fertility signs - basal body temperature, ovulation predictor kit results

How to start
Mark day 1 (the first day of full flow) each period
Count your cycle length from day 1 to the next day 1
Log daily for a few cycles to reveal your pattern
Note symptoms alongside dates so links become visible

What you learn
Your average cycle length and how regular you are
Your likely ovulation day and fertile window
Whether symptoms truly follow your cycle (the hallmark of PMS)
Changes from your baseline worth raising with a clinician

Why apps help

Apps turn scattered notes into predictions and charts that sharpen over time, and give you an exportable record for appointments.

Use the Menstrual Cycle Calculator for a quick estimate, and read why should I track my cycle.

Femora logs dates, flow, and symptoms in one place and predicts your period and fertile window from your own data.
