Prediabetic, metformin and TTC

Baillie • 24. Wife. Uterus Didelphys. adoptive mama. TTC rainbow

My ob/gyn ran tests last week and found that I’m prediabetic. Now I’m on a low carb diet, she told me I need to get my weight down or they “won’t be able to do anything” for me if I happen to get pregnant again, I weigh 209 lbs.... I miscarried in July but not because of my blood sugar or health at all. She put me on Metformin and told me it would help me lose weight and help me conceive. I’m just looking for anyone else who has actually had success with either of these.
