My last Period was between February 11 or 12 I couldn't quite remember it. We had oral sex February 24, We were naked and he fingered me and I gave him a BJ and now on March 16 I was expecting my Periods because it usually goes on a 32 day cycle but its been 3 days and i haven't received my Periods yet. I've been stressing out lately because of school works and the fact that I haven't gotten my period. I'm sure that he hadn't touched his semen near my Vagina to make sure that everything was okay but Could I be pregnant?
