pregnant?

okay ladies so trying to figure out if I could be pregnant Bc I’m not in the boat to be lol. so this was (according to my apps) a few days after ovulation. we were together and I blew him and he ejacilated and then he went to pee and I was told that urine can kill sperm so would any left over sperm in his urethra be killed? after tho about half an hour later we fucked unprotected for like a minute or two and he pulled out before he came and he came no where near my vagina. so should I be okay? I mean I was told and read that you can only get pregnant 24 hours after ovulation so I should be fine right?
