Used a condom, could I be pregnant?

Seun

So, I had my first time with this friend of mine. It wasn't planned or anything and was all with concent and all. We used a condom since the beginning and he finished outside. It was 2 days after my period so I wasn't supposed to be ovulating either. My period is late, and I'm worried even tho for what I know is very unlikely. Is there any chance I could be pregnant? I'm sorry if the question is stupid, I'm not trying to offend anyone.
