They usually stop metformin because they say it's been proven to cross the placenta. They had me on glyburide (spell check). They never said it was harmful they just didn't want to risk it causing me problems. And diet management and NST monitoring will become like religion lol.
I have type 2 diabetes and I had it even before pregnancy.Till my 3rd trimester I was on medicine-metformin and diet. From third trimester it is just going up.So along with metformin I am on two types of insulin every day.But as of now my baby is doing fine.I am 34 W 6 days.
