Why is my period late?

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.

Thyroid issues
