So i'm extremely worried, i'd just like to point out that i'm a virgin. Last week, me and my boyfriend were messing around and i was sat on top of him (on his stomach) with nothing on my bottom half, he then decided to jack off & he came. I'm now extremely worried at the possibility of pregnancy as i am showing plenty of signs but they also match up with pms as i am due this saturday. Any suggestions on what to do?
