hello madam, thanks for your query.answer to your question is no as well as Yes.NO because you have taken unwanted 72 which is a emergency contraceptive pill,and YES because a lot of people think that if a girl has sex during her period, she can t get pregnant. But it is possible for a girl to get pregnant while she is bleeding. This can happen for a couple of reasons: 1.Not all vaginal bleeding is a menstrual period. Sometimes a girl will have a small amount of vaginal bleeding at the time of ovulation — the time when she is most fertile. Girls who are ovulating sometimes have some vaginal bleeding that can be mistaken for a period. 2.Sometimes ovulation can happen before the bleeding from a girl s period has stopped or within a few days after her period is over. All girls can ovulate at different points from cycle to cycle, making it impossible for a girl to know exactly when she is most fertile. Because sperm can fertilize an egg for 72 hours (3 days) after ejaculation, having sex during a girl s period is risky.AND IT IS NORMAL YOUR PERIODS MAY GET DELAY DUE TO UNWANTED 72. Thanks Dr.Rahul
