To hit someone up is to try to borrow money, or to get a donation.
It is a slang expression, meaning "call me" or "find me". It has nothing to do with actually hitting/punching a person.
youre out from hitting
Well it could mean many things. In baseball hitting is called connecting the ball with your bat. In football it means to tackle a player. Hitting could also mean a punch.
When you start hitting
If by "hitting" you mean literally hitting, then no. You cannot get pregnant from someone hitting you. If "hitting" is meant as a slang term for sexual intercourse...then via anal penetration, no. Via vaginal penetration, yes, you can get pregnant.
