I know that after I took the Emergency Contraception I got my period, as it was due not to long after. I know I took the ec a few hours after sex but lately I have been experiencing really tender enlarged breasts, with hard nipples. I wouldnt be really concerned but my period is not due (sometimes I get this a week before my period. I'm really freaking out!). I dont know if I am being a hypochondric or whatever, but I'm starting to feel really worried. should i take a pregnancy test?
