Gestational Diabetes

I was diagnosed with this at around 28 weeks. I am now about 37 weeks. I started off with diet control, then metformin, then insulin 6units, then 8 units, now 10 units. My glucose levels still are not ideal. I am paranoid about still birth due to it. I have an appointment in two days. I don't know if I should mention my anxiety about a still birth or not. They always act like everything is fine. They've mixed me up with different patients multiple times and don't seem like they have time to deal with me. So I just go in, they take urine and blood pressure, baby's heart rate and that's it. I've never had or been offered non stress tests or anything else. I literally have no where else to go for prenatal carel. If I did, I would have switched in the beginning.
