Sex during fertile days ... Advice?

Ok so this past Saturday and Sunday me and my long term boyfriend had sex while I was considered "fertile", I'm not ttc at all! However, we engaged in intercourse for like a minute without protection before he put the condom on to continue and finally finish later on. I did make him pee and wipe off his penis before we started, and I was wondering could there be a chance of me getting pregnant? I did have a slight pregnancy scare almost 8 months back using the withdrawal method for the first time, but now I'm getting nervous again because of all the speculation that pre cum has sperm ... But I did make him pee and clean himself off? Help!
