Hi ladies!
I am 7w3d pregnant with twins and have been taking my metformin for 6 months now. At my RE appt yesterday, he graduated me to my OB/GYN. I told him I was to run out of metformin soon (today) and he said well have your OB check your glucose levels to determine if you need to continue on it or not. I do not have an appt there until next Wednesday and am nervous about stopping the medicine, even just for a week. He said I would be fine to discontinue use of it anyway.
My question I guess is, if any of you were on Metformin, did you stop taking it once you got pregnant? Before end of first tri?
TIA!!
