Diabetes and Pregnancy

I have type 2 diabetes. I have just recently found out I was pregnant again after having a miscarriage in August. I talked to the nurse about my blood sugars. I have been on a low carb diet since beginning of May. I have lost almost 60 pounds and my a1c went from a 11.0 to 6.0 on this diet. My doctor wants me to go to 45 - 60 carbs per meal instead of like 10 per meal. I don’t want to take more meds but if I up my carbs to what they are recommending then I will have to go on more meds. What should I do?
