Mine was high with both of my babies. Your Dr will tell you if you need to go on a special diet. But if you do go on that diet, remember that it helps protect you and your baby from the problems that come with gestational diabetes.
You should be just fine b/c you have prenatal care ;)
It depends. Maybe. Maybe not. It is sort of a grab bag. I watched a thing earlier about this woman that was in labor at 28 weeks with preeclampsia. diabetes and kidney failure....oddly enough they did a c-section and her and the baby were relatively ok.
