Insulin for GD

Olivia
I recently started insulin for my GD on Friday. I take my dose that I was told to and I honestly feel like it is makingmy numbers higher. I haven't changed anything. Still eating how I was. Even cut back on the amount of carbs they want me to eat but still getting all over the place readings. Today my fasting was 103, 88 after breakfast and 146 after lunch. My lunch was literally a salad of all veggies and a cup of soup I didn't even finish. Waiting to hear back from my office on this but anyone else experience this??
