How long is my period delayed when I take the pill twice? It depends on what kind of contraceptive pill you take and when you take it, so that you can deduce it. There are several kinds of contraceptive pills in the clinic, among which short-acting contraceptive pills are taken on the first day of menstruation, once a day, one tablet at a time, for 21 days, and menstruation will come 3-7 days after stopping the pills, patients who take this kind of contraceptive pills have regular menstruation and will not be postponed, and some women take short-acting contraceptive pills to adjust their menstrual cycle because their menstrual cycle is not allowed. If you take the emergency contraceptive pill, you take it during the first half of your period, so that after you stop taking it, you will easily have withdrawal bleeding, which takes 3-5 days to be completely clean. So in this case nighttime may be delayed for a week, which is caused by the side effects of the pill. If the emergency contraceptive pill is taken orally during the second half of the period, it rarely causes delayed menstruation.
