Why is my period late after the second month of taking the morning after pill and it was 4 days early the first month after taking the morning after pill?

Hello Anonymous,

Welcome to EmpowHER. Thank you for reaching out to our community with your question regarding changes in your menstrual cycle after taking an emergency contraceptive.

I am assuming you had a regular menstrual cycle before taking the morning after pill.

Changes in the menstrual cycle is a reported side effect. That would explain why your first period after taking the pill started earlier than expected.

It is possible that you suffered a hormonal imbalance as a result of the pill. The menstrual cycle is regulated by a precise balance of hormones. An ECP contains a high dose of levonorgestrel,, which is a synthetic progesterone.

Consider speaking with your gynecologist, who can order blood tests to check your hormone levels and best advise you.
