I know this question is on here a view times, but I am really worried about my situation in particular and hoping to get some advice. Me and my girlfriend were messing around one night (neither of us have ever had nor plan on having sex anytime soon) and just playing around. We were in our underwear, she had thin pajamas and a tampon in (I've heard it called dry sex) just kind of imitating sex. She said she was on the last day of her period and just had one in"in case". Anyway, I had a some pre-cum. I was wondering of she could be pregnant? It is now two weeks later and she has been sick all night once (however she just found out she has a sinus infection) and I am just really worried. I've been losing sleep and just would like to know if it is possible, what are the chances, and that type of thing? Please, please, please get back to me on this, I'd like to have some factual answers not just guesses.
