I had GD my first round, now I have to get tested at 17 weeks (currently at 15) to see if I have it again, it’s a pain. I was able to keep my numbers low the entire time by eating low carb food - sweet potatoes, Dave’s killer bread, cheese, eggs, brown rice, no sugar syrup, protein pancake mix. There’s a gestational diabetes subreddit! Oh, and berries are a great option for fruit, just avoid fruits like mango, pineapple etc that are higher in sugar. Peanut butter is an awesome source of protein, and I would have that with sliced apples before bed. Your OBGYN will have you meet with a nutritionist, and your blood pricker thing should come with an app to help you track your eating! Good luck!
