My boyfriend and i had sex right before i got my last period. we havent had sex since then. The month before that my period was late, just like this month, but this month i am 15 days late, we used a condom and he didnt ejaculate. Ive talked to a couple people about my situation and they said that it doesnt sound likely that i am pregnant. Everything seems to be normal. I dont really have any signs of pregnancy becides my boobs hurting alittle bit. Could it be that I am stressed and worried about it that my period is delayed?! Please help
