Patient's question:
Last month after having sex, I took the contraceptive pill, and my period came ten days earlier. Is this normal? Also, this time my period was very abnormal—my menstrual blood was particularly dark and the amount was very heavy. Is this because I took the contraceptive pill after sex? Is it urgent?Doctor's answer:
Because you are taking emergency contraception, this situation is definitely very normal. The active ingredient in emergency contraception is levonorgestrel, which, after taking it, can cause a significant impact on hormone levels in the body, making the body mistakenly think that menstruation is about to occur. Therefore, withdrawal bleeding may reappear in about a week. It also has a certain impact on subsequent menstruation, but it generally returns to normal after more than three months.
