the condom broke and i took the morning after pill like 12 hours later and it said something about have 72 hours to take it. well i got my period a week later for only 3 days and i was suppose to get it yesterday and i havent got it yet? but my body is acting like im pregnant..is this normal?
See these morning after pill contains progesterone which disturbs the normal cycle of menstruation.  So I don't think there is any need to worry unless you had any further unprotected Sexual Intercourse.  If you don't get periods even after 1 weeks get tested for Urine Pregnancy test.
