So, me and my gf were goofing around, and I touched her vaginal opening with the tip of my penis, unprotected, it had very little precum, all this happened on her ovulation day, as much as I've read there shouldn't have been any cum in the precum, I haven't cummed in 3-4 days, and plus I have urinated hour or half an hour before that happened, we didn't have any kind of vaginal sex... Is there any kind of chances of her getting pregnant? Thank you.
