2 doctors

Hello! I'm currently being seen by my regular maternity doctor but have also been sent to a maternity clinic doctor since im 31 weeks. Both doctors have been trying to send me for blood work and other tests but none are the same. Now my original doctor is getting mad at me for not getting her tests done or coming to see her but what I understood was once sent to a mat clinic they were your primary physician? Anybody know who to listen to or what to do? My original doctor now calls 2 or 3 times a day demanding i get tests and visits done but i don't know what to do since im with the mat clinic (she was never a good doctor either. Always called me fat and a wimp. Then made fun of me being afraid of needles) it feels horrible to be called lazy and a bad mom for missing things I didn't know I needed! My original one left a message on my phone basically telling me I was an idiot and lazy 😓

Update: I've already been in for i think 5 or 6 rounds of blood work where they took 6-9 vials each time so I decided to get only my maternity clinic blood work done. Even the blood techs asked why I'm getting so much blood work done and that it didn't seem right!
