I took plan b two days after unprotected sex and I was supposed to have my period the very next week. I had sex on a Saturday and took the pill on a Monday. I had mild cramps for two weeks and sore breasts when my period was supposed to arrive. A whole week has passed and marks 3 weeks after I've taken the pill and now I don't have any cramps or soreness. I am feeling very wet down there but that's all I have right now but I'm scared because there's no sign of period. I took the same pill two years ago so I don't use it regularly or anything. Could I be pregnant?
