First Time

So today I lost it to my boyfriend. He pulled out about a minute before he came and he was wearing a condom. The condom was kind of pulled down about an inch maybe two when he pulled out but not too bad. I'm 99% sure nothing got in me but I just want a second opinion. I think I'm just paranoid because I made him check the condom to see if it broke or anything and we know for sure it didn't. What do you think?
