I have always loved the saying that you can change who your care provider is but you can change who your care provider is. Meaning, it's a lot easier to transfer your care to someone who respects you as a client/patient than to try and undo 30 years of biases and habits in your 20 minute prenatal visits.
My first January client is in this predicament. She feels the backup to her primary care provider is not hearing and respecting her concerns about an issue, and it leads her to question how well her concerns were met by her primary in the first place. She's in the window and she's considering switching providers. I hope it turns out to be a big misunderstanding but I respect her ability to advocate for herself and her priorities for her birth.
