Sex before ovulation

What are the odds? We had sex unprotected on a day that according to this app was my ovulation day. But according to my own symptoms I think I ovulated 3 or 4 days after sex.

So if I am correct and it was 3/4 days after. We should be good right ? Lol. I’m older , I know how this all works. I’m more looking for personal experiences with having sex once 3/4 days before ovulation and either not getting pg or getting pg.

Thanks!
