Why do periods sometimes come late?

Common Reasons for Late Periods:

- Pregnancy: If you haven't had your period for a week or more and have had unprotected sex, take a pregnancy test. Even if you think there's no way you could be pregnant, it's always best to rule it out.

- Birth control: Some birth control methods can cause your period to come later than expected, such as hormonal pills, patches, or injections. If you're using a birth control method that could cause a late period, it's best to talk to your doctor if you're concerned.

- Stress: Stress can affect your hormones and cause your period to be late. This is often temporary and your period should return to normal once the stressor is removed.

- Diet and exercise: Extreme changes in diet or exercise can also affect your hormones and cause your period to be late. This is often temporary and your period should return to normal once your routine stabilizes.

- Illness: Some illnesses can cause your period to be late, such as thyroid problems or diabetes. If you have an underlying medical condition, it's important to talk to your doctor if you're concerned about a late period.

Remember: Periods can vary in length and timing, and it's normal for your cycle to occasionally be off by a few days. However, if your period is more than a week late or if you're experiencing other symptoms, it's always best to talk to your doctor.
