Hello,
On 27th of October I and my girl friend had sort of sex that my penis head goes into her vagina (not completely, also not in a right place). The sex position was “reverse cowgirl” which she was on top of me and our faces were both toward the ceiling. In the orgasm moment I tried to ejaculate my semen away from her vagina but it ended up on her butt. But because I wasn’t completely sure that even a little semen gets into her vagina, she took a shower right away. 1 week after this accident, she had her period (on 2th of September) also on 20th of September she got her pregnancy test and the answer was negative. But still we are nervous. I feel a little stupid to say this and I know this cannot be a sign, at least this soon, but because of changing her weight and shape of her belly I am too worried that still is there any problem? Her period should be around 1 to 5 of October. So does she need to do the pregnancy test again??
