37 weeks pregnant with GD and worried.?

My OB sent me to a specialty doctor for high risk pregnancies for an ultrasound to see how big my baby girl is getting. After finding out she's already 7lbs 4oz the doctor tells me (keep in mind this doctor was rude and made me cry once what he said sunk in.) That because of my sugars being a bit high more recently he wants me to come back in 2 weeks for another ultrasound to make sure she has a heartbeat and that she's moving. I am actually 37wks tomorrow btw. He also wants me to go for non stress tests 2 times a week instead of the once a week I have been doing since I was 33 weeks. I always pass my nst with flying colors, she's always active. I don't understand why he would say something like that to a pregnant woman. He made me feel like she's going to be a still born. I cried my eyes out when I left the office. I had my son 2 1/2 years ago and had gestational diabetes as well and my sugars got all wacky at this time as well and he's a perfectly healthy little boy. They never treated me like that with my son. Im furious and think I am going to tell my OB how the specialty doctor treated me. He was miserable and scared the hell out of me. I just want my baby girl here asap now bc of how he scared me.
