Can u get pregnant a day after ovulation

I’m just curious or it has to be on the day i ovulated to get pregnant we had sex one time when i ovulated so is that i high chance i could get pregnant or if we did it more than once would it be a better chance ? Right now i hope i don’t get pregnant from him he irritates me always gotta attitude about something we just got into it earlie this morning smfh . I’m just so done over something stupid really .. but yet he gets mad because i rolled my eyes again at him over his house n my face was frowned up when i was talking to him. Like just typing this is so dumb anybody would’ve been left 🙄🙄
