Ok, me and my boyfriend were dryhumping but then we decided to take off our pants and do it like that... we have NEVER had sex before and i was on my period like a day before that and was just finishing up with it that day... his penis went maybe an inch inside of me but i had a tampon in. any chance the precum could get me pregnant. Im really stressing out.

Also my friend one time was doing the same thing with her bf a day after her period and a little but of precum may of gotten on the out side of her vagina or around in but i dont think ever in it. she has never had sex either. how much of a chance is there of her getting pregnant? I've heard a very unlikely chance?
