Don’t like your doctor......

La

Ok so I live in Brooklyn ny I go to this ob gyn that is in downtown but it’s a huge office with like 5 different gynecologist I’m 7 months now and since I’ve been going there I’ve seen 2 different doctors and another doctor I’ve seen once ....I just found out today that the doctor I seen one time (who was a complete bitch by the way ) is delivering my baby ... I purposely was making my appointments on Friday instead of Wednesday so I don’t have to see her

Today the receptionist from the clinic calls and tells me if I can come in today to see this dr cuz she will be delivering my baby ....I told her no my appointment is for Friday and I’m busy today can I explain to the dr that I usually see on Friday that I don’t want that lady delivering my baby ???
