Condom broke but he pulled out right away

So my boyfriend and I were having sex and i felt the condim break. He pulled out less than 5 seconds later and we didn't continue. I am slightly worried but according to eve, this happened 2 days after my fertile window was over. I am not too worried cause something like this has happened before except it was worse bc my bf didn't realize it broke until he pulled out to cum(and of course i didn't end up pregnant) I know pre cum can get you pregnant but there shouldn't be any left over sperm cause this is the first time we've had sex all week. what do you think my chances are?
