Chances of Pregnancy?

My boyfriend and I had sex on November 2, which was 2 days after my period ended on the 31st. Im not on any kind of birth control, and we usually use condoms but it was spur of the moment and it just didn’t happen. He didn’t pull out. We’re 22 and 23 and he has 2 kids and I have 1, so it’s not like we don’t know what causes kids, but I just want to know what everyone thinks the chances are that I could have gotten pregnant, that close to the end of my period, and according to my app, it was about 4 days before ovulation, considering it’s too early for me to test yet, but my mind is racing.
