Are there careers in the medical field that don't require 8 years?

I’m a pre-med major but I found out today that my GPA is 2.9, and I realize that I’m going to need to work really hard to get my GPA higher and get into med school, but I’m worried that I won’t be able to get a high enough GPA to get into medical school, and I’m looking at other careers in the medical field and I’m just wondering what else I can have a career in in the medical field that doesn’t require 8 years of school?
