I'm 19. My last period was aug 6. on aug 10 a friend and I messed around; my underwear remained on the entire time and he was only naked for a little bit and as far as I know he wasn't near me at all. There was no wetness on my underwear... but he did pre-/ (im not sure) into my hand but then left for the bathroom. Since then, I've been really stressed. I got what I think is the normal vaginal discharge around ovulation around the aug 21st maybe. I was really bloated then and my breasts were tender especially on the sides. Every time I was hungry I would eat a little bit and then feel really full. I also had these weird cramps that seemed like sharp pains in my lower abdomen that would subside after a few seconds. Starting the end of last week I've felt a burning sensation in my breasts and in my lower abdomen.

I don't think there's anyway I could have gotten pregnant. There was no penetration and I've never had sex before. Could stress cause these symptoms (my period is supposed to come around now) or is there some way that I got pregnant? Please help.

Aren't you due for your next period? Those sound like indicators of an upcoming menstral cycle to me.

*edit*
If that's what really happened, chances are very low that you could have gotten pregnant.
