Okay I'd really like confirmation that I'm just being paranoid. My boyfriend and I had sex for the first time on March 2. He wore a condom the entire time and never ejaculated...it only lasted about 5 minutes anyway because it really hurt. My period came the next day and lasted as long as usual. We haven't had sex again since then but my next period is now a week late...should I realistically be concerned about pregnancy, or am I making my period late by worrying so much? I'm 18 and just got into an ivy league and a baby is NOT what I want to think about. Please help.
