My ex and I had sex almost 4 weeks ago (it will be 4 weeks tomorrow). The day were had sex I ended my period. Things were getting steamy and were were trying different possitions, but the condom broke and he came inside me. I haven't missed a period yet, my period is supposed to start today. I feel naudeous all the time, and I cant keep anything dowon, I can't sleep. Does anyone on here think I'm pregnant?
