Okay so this might seem really weird and its something that I have never done and for some reason I did it this time. I had sex with my best friend on may 28th but on may 31st - June 6. without a condom I started to have sex with my boyfriend and now I'm pregnant and I have no idea who the dad is. I'm really scared my lmp was on may 22. So when did I get pregnant .please help I really need to know.. thanx
