Ok my girlfriend was sucking me off and I didn't had a condom. But I didn't cum yet. So I push my penis head inside of her and she was wet but I didn't cum yet, but I was wondering because although I didn't cum after she finish sucking me off I wasn't sure if I precummed. And like she had her period late last month. And now she's 5 days later than the date she got last month. I'm not sure if she's pregnant. Please help.
From the situation you describe, it is unlikelythat she will be pregnant but not impossible. If you do not want to get her pregnant then you should never insert your unprotected penis into her vagina (unless she is taking contraceptives)
Just f**k her throat or ass! Or f**k mine lol!
