If a guy cums and he might have some on his hands then wipes it off and fingers me could i get pregnant?

Not likely: Dry fingers don't create babies. That being said, life can surprise you sometimes. If worried, can do a pregnancy test in 3 weeks (if the next normal regular period doesn't happen). A home urine pregnancy test gives a reliable result 3 weeks after sex, or 1 week after missing a period. If done sooner, a positive result is likely real, but a negative result may be due to testing too soon.
