On the first of September my boyfriend and I had unprotected sex and he ejaculated inside me. same thing on the 2&3 and then the 4th I started my period, it went through the 8th. We had sex Wednesday and Thursday multiple times a day; again ejaculated in me. There a possibility I'll be pregnant in a few weeks? Cause I haven't felt right since the first couple times it happened but I started my period after so I figured i wouldn't be pregnant or get pregnant. Help?
