So I am 16 !! And I had sex with my boyfriend about two weeks ago and Im susposed to get my period in two days but we had unprotected sex... and he finished right on top of my vagina and he wiped it off and then I went to the bathroom and got a baby wipe and wiped more off just incase there was more then I peed but recently I feel bloated !! Like my stomach doesn't feel right but I feel like I'm paranoid !!! I don't know and I'm freaking out !! What do I do
