Will my girlfriend pregnant

i make out with my gf, and i had an ejeculation trough hand -job, and my sperm spilled on my hand, after that i wash it (not so properly) and wipe it with towel.

after about 5 minutes, i do fingerin to her (without my fingger penetrate her vagina)...

is there a possibility she'll get pregnant?

Answer: Yes, but not very likely. Anyway, since a pregnancy is caused by semen getting into the vagina, be a little more careful next time.
