Chances of pregnancy

So I had unprotected sex, the condom broke and we didn’t know... on the 7th this happened but tech the 8th at like 1 am and on the 13th I ovulated(by the way I’ve never had anything happen like this but when I woke up the morn on the 13th I got like a snapping pain I thought I was gonna faint from it, it lasted about 5 seconds) so what are my chances of pregnancy? Is there a high chance since I had sex the day before my fertility window started?
