Pregnancy?

Okay so I know on ovulation that’s when you have high risk of getting pregnant. I had sex on the 1st my baby finished inside earlier that morning, in the middle of the day we also had sex this time he didn’t finish inside me but he did finish on top of my pussy and dropped down to my butt as well. I just want to know how likely is that I could get pregnant by that one time. Is it the same risk as having sex all the time during ovulation or is it less likely I could get pregnant ?
