"i&#039;m writing this review to calm the minds of others who are in the same boat i was until today (the day i got my period). i have taken plan b on 4 separate occasions in my life- split up over seven years. this last time was different for a few reasons: i was ovulating during intercourse, used the pull out method, and was over the supposed 175 lb &quot;weight limit&quot;. timeline: first day of last period- march 19. day i had sex- march 29th. day i took plan b- march 30th (14 hours later).  the  day i got my period- april 11th. i had cramping the entire 12 days after taking plan b before getting my period, different from the last three times i&#039;d taken it in my life. my advice: relax. take it asap after sex. and get a z pack to protect against stds as well."
