I'm currently pregnant also. I'm almost 13 weeks. My obgyn has me checking my blood sugar with a glucose meter 4x a day for two weeks to check for gestational diabetes. My obgyn also sent me to a diabetes education class to learn how to use the glucose meter and also what foods to eat. Maybe mention this to your obgyn as a possible option for you. You may also want to find an obgyn that has more experience with treating bariatric patients. Good luck and congrats on your pregnancy ?
