Ok so I took plan b twice in one week, the 17 of Feb then again 21 of Feb right after unprotected sex. Got very heavy period the 23 of Feb, so I assumed I didn't have to worry about pregnancy. Started birth control the 1st of March, have been experiencing strong cramps and light spotting which I read was normal side effects of bc, my stomach had been a little gurgly yesterday and today, is it possibly because of bc, or should I be worried about pregnacy? Please answer, no judging please.
