Doctor shopping

Am

I’m thinking about switching doctors. I’m more than half way through my pregnancy but I just feel like I didn’t connect with my doctors the way I wanted to. Anyone have any advice for how to go about this? Do I continue to see both doctors until I’m committed to one? My first doctor is supposed to be billing me for appointments each time I go but I’ve been 3 times and they’ve never taken my card. I don’t want to get hit with a bunch of charges for different places because I shopped around….
