Feeling huge!

Joee
I am 33 weeks tomorrow and I was diagnosed with GD. I am measuring a week and a half big but I had the same issue with my first baby. It was just excess fluid and I didn't have GD with him. But I feel like and am worried that this baby will be big. I have kept my numbers under control with diet and exercise and only have to take a pill at night to help with my fasting blood sugar. I do have an ultrasound in 2 weeks to check the baby and my placenta because unfortunately I have a low laying placenta. I am just more nervous and worried with all the issues (although small) I have had. Has anyone had the same issues and had baby and delivery be fine?
