Patient's question:
The last time I had sex with my boyfriend, he didn't wear a condom, so later I went to a pharmacy to buy and take birth control pills. But I noticed that after taking the pills, my period hasn't arrived for several days. Therefore, I want to ask, how long can birth control pills interfere with your period?Doctor's answer:
Emergency contraception pills may interfere with two or three menstrual cycles. A delay of up to one week in menstruation is also normal. You should wait and see first. If your period is delayed for more than a week, you should first use a pregnancy test to check for pregnancy. Emergency contraception pills only provide maximum contraception, and there are also a few people who may get pregnant. As long as it is not pregnancy, and the period does not come for less than two months, consider medication to regulate it.
