Gestational diabetes. . Fasting

So I was recently diagnosed with gestational diabetes and was told to monitor and check 4x a day. .my numbers have been at range throughout the day. Unfortunately, my fasting levels are what tend to be the highest. . Do any of you ladies have GD? Any tips on how to lower your fasting numbers? The dietician and I are wanting to focus on a diet/meal plan before getting on medicine. . I know that later on in my pregnancy I might have to get on meds but for time being I want to focus on just eating right and try to control it that way. I'm seeing the dietician next week so I guess I can bring it up to her and see what she suggests.
