Hi there. You can not get pregnant from what you describe. Vaginal intercourse is how someone gets pregnant, not from fingering or dry humping. good luck
Sperm can survive in semen outside of the vagina for a few hours. If his hands were completely dry, you would not get pregnant. Even if there was the teeniest bit of semen on his fingers, the sperm inside would probably not survive the journey all the way up to your cervix. You would also have to be ovulating for any sperm to fertilize an egg. If it was a few days before your period, you were far beyond that time frame.
