So, I Had Ejaculated Into My Pants 30-50 Minutes Before

So, I had ejaculated into my pants 30-50 minutes before this happened. I put on a condom (that didn't cover the nut area as normal) and I wasn't exactly penetrating my girlfriend's vagina, we were just rubbing on each other's genetic organs. I am worried because I don't know if my sperm managed to go that down, and she touched my nuts with her vagina. Is it possible that she gets pregnant? She wiped off her vagina after that. Also, 30-50 minutes had passed since I ejaculated in my pants. Is it possible that my sperm was still there to find its way into her vagina?
