Gestational diabetes

Ashley • Miscarriage 2/2018* Rainbow baby due 9/2019🌈❤️🥰

So ladies my doc told me my sugar was 153 and it is suppose to range from 65 to 139 so I have to go to the hospital Friday to get checked again for gestational diabetes. I’m so scared I don’t want that :( what can I do to help that if I do have that. What foods is best plz help a girl out. My dad and mom both have diabetes and I don’t want my baby to get it. Any opinions I would appreciate 🙏
