my chances of being pregnant???

Okay so me and my boyfriend had protected sex one night. We hadn't seen each other in awhile so...thirty minutes later we had sex again. Except this time, the first half we didn't use a condom. We just were being irresponsible and horny and our senses kicked on half way through so we paused to put on a condom. But then I checked eve and found out my fertile window started the next day...my sex ed wasn't great but I do know that it's possible to get pregnant from precum picking up any leftover sperm. I also know that it's unlikely. So I guess what I'm asking is what are my chances of being preggers right now?
