My boyfriend and I had unprotected sex. It was our first "real" sex, the first ones really hurt so we didn't continue. He thrusted for only like ten times and he felt he was about to ejaculate so he pulled out and a second or two, he did ejaculate. My average cycle is 26 days and I had my last period Jan. 23, 2016. We did it a few hours ago, Jan 29, 2016. Help me please
