Low GPA, Teaching during gap year

I graduated from college with a 3.2 GPA and will be taking the MCAT soon, but instead of doing post-bacc, I wanted to teach during my gap years because it has always been a passion of mine. I’m currently teaching high school as a Teach for America corps member. Do I still have a chance of getting into med school if I apply this cycle? Or does a post-bacc still seem like the best option?
