Stressed and worried

Last night was my first time, but before we did it I have him a bj, and he ended up getting cum on my hand. I wiped it off and made sure to be careful not to touch my vagina (probably my irrational fear of getting pregnant) but I’m not stressed that I could, I’m probably just worried about nothing. But if we did wipe it off and our hands weren’t sticky and it had been a while. If one of us did touch down there could I get pregnant?
