Okay this may be TMI (I seem to have a lot of questions that are graphic lol) but I just had my daughter August 18th and I was told to wait six weeks before sex or anything. Well yesterday my boyfriend and I were taking a shower and both got a little into the moment and he started rubbing up against me and almost put it in all the way but I stopped him because I felt too tight and it was hurting (I had to have a lot of stitches down there) and I knew I wasn't supposed to have sex for another couple weeks anyways. I have been so used to having sex and messing around without protection because I've been pregnant so I didn't even think anything about it but now I'm worrying myself because I've been told you are more fertile after having a baby and I've also heard you can get pregnant off of precum. We fooled around for about 20 or 30 minutes with him rubbing himself on me.. could there be any possibility of me getting pregnant again? I'm probably just freaking myself out..
