Is Pregnancy Possible After Contact With Precum And Not Being Sure If I Washed My Hands?

I went to the bathroom the other day and I had precum on my penis, I dried it with a piece of paper (but it felt wet) and then touched my shaft. I proceeded to wash my hands (dont remember if I really did) , fifteen minutes later I fingered my girlfriend (my hands were dry and I put saliva on them). Is there a chance she might be pregnant?
