Uncontrolled Diabetes and Pregnant

I found out I was pregnant at 5wks7dys. I stopped all my meds that day (Sunday) called my dr Monday. She advised stop everything except Metformin. I made an appointment with an OB, but even after saying I had uncontrolled diabetes they still wouldn't see me until 8wks. I went to my own dr. And she put me on Insulin. My numbers are still getting as high as 250 and the lowest was 165. I see her again on Thursday, but I am terrified that I am killing my baby. I have drastically changed my diet including completely cutting chocolate milk and Caramel Macchiatos which I drank every day.  I eat a scrambled egg and a slice of toast for breakfast and a salad for lunch and my numbers still get high. Anyone else had uncontrolled diabetes at 6wks and had a healthy baby?
