Will Touching The Vagina And Labia Minora With Ejaculate On The Fingers Lead To Pregnancy?

we were engaged in rubbing our geniatals, she was on my lap and we were fully clothed and after sometime there was a small stain on my pants of precum and i tried to rub that with my fingers and after a gap of 20/30min i touched her vagina surface (clitoris and labia minora) she was also wet So will this lead to pregnency?
