Pregnant from fingering with precum?

I was messing around with this girl and I may have precumed, I know there was no real sperm, and my pants were on. I do not remember touching the precum or going in my pants at all, but just thinking about it gets me worried. I later tried to finger her, but honestly her pants were really tight and I basically think I only made it to the top part where the lips start to form, I do not think I even made it to the vagina and I definitely did not go into the canal at all, I basically just rubbed the surface with no real penetration because I could not make it to her vagina. I know there really is no chance she got pregnant from the possibilty of me having dried precum on my hands when i did not even make it to her vagina, but i am still worrying for some reason
