need to change doctors

Okay. So recently I have medical and was under my moms insurance I had to cancel with my mom in order for them to see me under medical, I was going to this hospital to get my ultrasounds done since I'm having twins and I'm a high risk pregnancy. Since my insurance under my mother was cancelled I have not been able to get an ultrasound for about a month because my doctor is stupid and she had to sent a feferal else where and she didn't do it and I've been calling back and fourth with her and the place I'm supposed to get my ultrasound done and they have not received the proper work for them to see me. I am so frustrated and I want to change my docotr but also don't because I'm almost 6 months and I feel like it's too late. This would be the second time I'm changing my docotr too 😒
