What are the chances?

Ok so i lost my virginity on the 1st, and we did it for like 5 minutes, he didn’t go deep, he didn’t cum or precum, and he condom went well. The second time we had sex on the 3rd, we did it for 20 minutes, he was very deep, he still didn’t cum or precum, but the condom broke but we immediately pulled out and put on a new one. I took plan b later that night because i was on my fertile window. i haven’t had any discharge since and my period isn’t supposed to come till the 18th... what are the chances i could be pregnant?
