Periods are generally referred to as menstruation. Bleeding after taking emergency contraceptive pills belongs to withdrawal bleeding, and it is possible that you will still have your period on time, or that you will have your period again in a month’s time. After taking the emergency contraceptive pill, some women will cause irregular vaginal bleeding, which is withdrawal bleeding. If the amount of bleeding is small, then the next menstrual period will still follow the previous menstrual period. However, some people have heavy withdrawal bleeding, similar to that of menstruation, and that can be treated as a menstrual period. Wait a month before having your period again. After retreating bleeding, the time of menstruation is different for each person, so observe the bleeding time and the amount of bleeding. Pay attention to keep pubic hygiene, change and wash underwear regularly, etc. This medicine should not be taken regularly, and you should pay attention to the use of condoms and other means of contraception. The specific situation needs to be decided in an interview.
