What happens to Penny in Dirty Dancing Movie?

Penny got pregnant by that boy Baby’s sister was chasing around. Robbie Gould is the character’s name. Anyway, the doctor she hired to do the abortion was a quack. He didn’t know what he was doing (I think one of Penny’s friends called him a “butcher”) and his instruments were dirty. She got some kind of infection or sepsis and she might’ve died, if Baby’s father hadn’t been there.
