Advice

I recently got off of birth control for the way it made me feel. I in no way intend to have kids right now but if it happens it happens. My fiancé used to cum in me constantly when on birth control & he says he misses the sensation of it. We’ve been doing it with condoms so he could get the pleasure of cumming inside of me but he says it isn’t the same. I was wondering how likely it would be to get pregnant if we had sex the day or 2 after my period and he cummed in me? Have any of you personally gotten pregnant from the day after sex? I read about it but I’ve never actually met anyone who has. So I’d like to know, I really just want him to feel like I care about his pleasure too.
