Comdoms

Okay please don’t judge but I’d really appreciate some opinions.

So I was having sex and was on top when he came inside of me. I think I got off of him about 4-5 seconds afterwards. He was wearing a condom that I put on and checked. There was no tears and it was perfect size. What are they chances of me getting pregnant after this? I’m just having OCD about this because I’ve never let a person come inside of me. :)
