Is it normal to get your period after haven taken the EC(emergency contraceptive)pill?
"Temporary disruption of the menstrual cycle is also common and may manifest as early or late periods, spotting or breakthrough bleeding, and (less commonly) missed periods. The primary mechanism of EC is delaying ovulation. Menstruation occurs, on average, 14 days after ovulation, so delayed ovulation results in delayed menstruation. Suppression of ovulation may cause anovulatory bleeding, which could manifest as an early period."
You should have a pregnancy test ... just in case
Yes that is what happens when you use it.
I used it once and I did not get any bleeding but the package instert said that there may be. Why not call your doctor orf phamacist and ask them? You can always call a different pharmacy than the one you go to just to be annonymous.
