me and my girlfriend had protected sex three weeks ago (feb 20), and while were having sex, the condom slipped halfway off. as i was cumming, i was pulling out but i was still inside of her. the condom was still halfway on and the tip was filled up. she had her period 4 days before we had sex. 2 weeks after sex she was complaining of some pregnacy sympotms that turned out to be the stomach bug. Now after three weeks she says she is totally stressed out about it, shes exhusted and has alot of the typical sympotoms( fatique, tender brests, mood swings, . shes worrying herself sick and has been barely eating. i know she is stressing out about the situation. what are the chances that shes pregnant or could the stress be causing these sympotms. we are both 18 and really really scared. what do you think
