See doc. Would check with your doc for exam nd possible testing.
Did you take the. Plan b within 72 hours of the episode of vaginal intercourse. Potential side effects w emergency contraception include menstrual flow changes (spotting, bleeding, early or late period). Take pregnancy test ; notify dr if your period is 7 or > days late. There is a good chance this is due to use of plan b.
