On the 10 & 14 we had multiple sessions

On the 11th we might’ve had a slip up but neither of us are really sure tbh. He said he *thinks* he did (pullout). And that’s not confident enough for me. So I’m pretty sure he might’ve not pulled out in time with as much precision as the other times. When we’ve had multiple sessions he didn’t pee inbetween and there was hardly 30 min in between the sessions. So my question is because of this information is there a chance I could get pregnant or would it still be unlikely ??? Just was thinking about it tonight. And kinda getting worried about the possibility. I don’t believe in Bc because of my religion so pls don’t suggest that. Thank you 🫶🏼🫶🏼
