I had sex with a friend and it was totally spur of the moment. We used the rhythm method, but I did notice that during foreplay that he excreted plenty of lubricant. I started my period two days later and i'm wondering if I could become pregnant? I already have a six year old and I want more children, however I would like to settle down with someone. I don't want to trap him, but I need some sort of direction so that I don't drive myself crazy for the next couple of months!!!!!!!
