I missed one question, it will do you no harm to cutdown on bread, potatoes, rice, and pasta. This will reduce your carbohydrate load and your blood glucose levels. But bear in mind that you are pregnant so you will need to ensure that there are sufficient nutrients in your diet to grow your baby. Eating meats, cheese, eggs, and, in general, above ground vegetables should ensure that there are. I still don't think you need to worry about your blood glucose but reducing carbs slowly will help reduce blood sugars and your anxiety.
