Following diabetic diet during pregnancy

Cross posted in another channel.

 My husband just recently found out that he is diabetic and, of course, needs to change his diet. If I am being completely honest with myself, I also was and usually am eating pretty badly. I am 20 weeks pregnant and 193 pounds at 5”6’. I’ve gained about 12 pounds since I got pregnant.

I will ask my doctor about this, but has anyone followed a diabetic diet while pregnant? It would just be easier for both of us if we ate the same food and I don’t mind changing my diet and adding things if I need to.
