What do you eat?

So I am obese. I know a lot of people say don’t lose weight while pregnant but since I’m 70 over (I’m also very short, having pains) my doctor said slow and steady is okay so I’m trying to maintain my diet changes while growing our little blessing. Hopefully I can still lose some weight along the way even if it’s only 10 pounds. The problem I’m hitting now is my nausea!!!! I’m finding I can eat carbs okay. Bread, beans, crackers…protein makes me sick, cheese, sauces, I can eat some fruits. Just trying to find some meals I can make to help me stay on track vs eating a box of cheez its 😅
