What can I do?

I am only 18 weeks pregnant, got diagnosed with GDM super early as I have a history of it. I woke up with a fasting of 106, could anything in my diet be contributing?? What I eat doesn’t fluctuate too much, so this is what I had yesterday.
Fasting of 94 @10a
11a Breakfast: 1 slice of WW toast, 1/2 avocado, 1 egg with sausage. 23g carbs
12p Coffee with soy milk and sf creamer. 10g carbs
4p dinner: 1/2 cup WW Mac n cheese, pear skin (leftovers from toddler lol), 1 bell pepper, 1/2 cup cottage cheese.
7p snack: Triple Zero Greek Yogurt with granola.

I just want advice please!!
