Is there a possibility of pregnancy if I had sex with my boyfriend on 25th (a one off time without a condom because we had no money to buy more) and he pulled out (he’s never finished with anyone else before me, I don’t know if that means his sperm would be more stronger/fresh or whatever???)

I’m in my fertile window and we had sex unprotected a day before I started my fertile window and it’s 3 days until I β€œovulate” and he’s just wondering if there’s any chance I might be pregnant or end up becoming pregnant.

I told him I can’t find out until two weeks later so he understands that.

He has Aspergers and gets worried very easily and I just need some advice and tips on what to do as I don’t want to scare him and worry him even more if I am or anything because he’s already really worried and obviously regrets having sex unprotected for the first time with me.
