I’m 15 and i just had sex for the first time yesterday but it wasn’t planned. my bf came over just to hangout then we had sex and i don’t regret it at all but we didn’t have condoms and we didn’t think about it until he was abt to cum, he pulled out and did it on my stomach but is there any chance i could be pregnant? it was also halfway through my fertile window.
