My boyfriend and I had unprotected sex 3 days ago and again 2 days ago. Both times we had multiple orgasms while he was still in me. I began what looks like my period yesterday. Normally I don't cramp during my period, but I do now. My breasts don't feel sore or anything but sometimes my lower back hurts but not too often. Is there a chance that I am pregnant? Would the multiple orgasms effect that? Also I don't have health insurance because I can't afford it, so I don't know what to do there. Please help!
