I had a 1 heavy day period &3 days of spotting. i took plan b an hour after unprotected sex. should i be worried or is this normal ?

PlanB: Your bleeding and spotting can be normal with plan B. Not to worry

Emergency Contracept: Emergency contraception can certainly throw your period out of whack. 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.
