I had my sperm all on my hand and didn't wipe it off or anything , it dried on its own after 10 min . i then fingered my girlfriend hard . pregnant?

Maybe (not) . . .: Only way to determine if someone's pregnant is to do a home pregnancy test (available at most drug stores) or wait 9 months. In the future, avoid unprotected sexual activity. In other words, wash your hands (always a good idea). Wear a condom (not on your fingers)(also useful to prevent sexually transmitted infections/diseases). Consider hormonal contraception (this is for the ladies).
