Ok... My bf and I had protected sex the other day. I know for a fact that he didn't come in me. But what i'm worried about is the pre-ejeculation that could have come before he pulled out. I know the condom protects that but he had to re-adjust the condom several times (we think because I was particularly dry that day) because it was slipping out of place. What are my chances that i'm pregnant from the pre? I know that there is lubracant in the condom so that could have killed some of the pre... But im just being extremely paranoid... Please help me...
