I had gestational diabetes, and I had a miscarriage 7 months ago. It was an IVF pregnancy. Since then, my blood sugar has not returned completely to normal. I was taking Metformin. For the past 3 months, without any medication, my fasting glucose has been around 101–102 mg/dl, and my 2-hour post-meal readings have been between 120–145 mg/dl. My HbA1c on July 16 was 6.9. I have been checking my fasting glucose every 15 days, and it has consistently remained around 101. Should I continue taking the medicine, or has my gestational diabetes returned to normal?
