Switching OBs mid-pregnancy?


Has anyone had any experience with switching OB's mid pregnancy? I'm 21 weeks and I'm super unsatisfied with my current OB. I always sit in the waiting room for at least 45 minutes past my appointment time and he is always obviously just trying to get me in and out since he's so behind. I had my anatomy scan today and he didn't explain a single thing to me, just took several quick measurements and told me to come back in 4 weeks. His office is also very out of the way from where I live, and I know that if I go into labor during rush hour it will take me a solid hour to get to the only hospital he delivers at.

I'm a little reluctant just because I'm over halfway through my pregnancy and it's a difficult process with my insurance.
