Gestational diabetes late pregnancy ultrasound

Bi

My sugars have been fairly under control with diet with an exception of a few days of highs and a few days of lows. When talking to my doctor last week she said that usually they do an ultrasound to check baby when the mother has diabetes but since mine seem to be under control there is no need. I personally would feel better having had an one since I haven’t seen him since 20 weeks. Anyone else have GD? And if so are you getting an Ultrasound?
