My previous period began on 13/07/2010 and ended on 17/07/2010 and my cycle is always every 28-30 days, but now I have late 6 or 7 days for my next period of August 2010 (36 days afte rmy last period). My breast is swallen, I have period pains but no blood. I dont have any other symptoms. We had unprotected sex on 23/07, and also on 26/07 with ejaculation inside me, also we had regular sex the days after that without ejaculation inside me. I am not under streess and I didnt put any extra weight and I suppose this cannot be the factor of delaying. Should I make a test? or is too soon? do you believe that I am pregnant?
