Is this bad ?

I know I know y’all girls hate responding to stupid ass questions, but I just need to get this off my chest. Anyways me and my boyfriend had sex while I was on my fertile window, I had a 15% chance to get pregnant, even though he didn’t cum I keep worrying because it was a high chance for me to get pregnant. so I was wondering if it’s a possibility of me being pregnant even though he didn’t cum, oh and no we did not use protection (dumb ikr). Like I said I know that this is a dumb ass question, I’m just asking that’s all so hate me all you want ig ._.
