i have mild gestational diabetes
I was gestational diabetic. I do take enzymes and when not pregnant, my BMI ranges from 18-19 (nearly "underweight") My sugars were so out of whack I did go on insulin. I was terrified of the finger prick at first, so you can imagine how I felt about insulin. But you do what you gotta do, right?
I managed just fine and actually preferred insulin over a low carb diet. Diabetes is all about carbs. Through trial and error we figured out how many units of insulin I needed per number of carbs. (turned out I needed 1 unit of humolog per 15 carbs, which is a really low dose) I did have to count carbs, but I could eat anything I wanted. The more carbs, the more insulin. My numbers were always within range that way.
My OB referred me to a gestational diabetes team at my hosptial called "Sweet Success". They are a group of dieticians that monitor my blood sugars and met with me once a month I believe. They are not used to seeing CFers (I was the first!) so their diet is strict low carb. But they did work with me on my needs in combination with my CF nutritionist as well. It might be worth a visit to see your dietician (cf dietician or a diabetic dietician, or both!)
I don't know much about pre-term labor. I went full term (never went into labor) 38 weeks with twins. One baby was large (7#6oz) and one was small (4#11oz). The size difference is rare, but happens sometimes with twins. I was never worried about pre-term labor. I figured if it happens it happens. I did have a scare at 34 weeks, but a shot of terbutaline stopped the contractions (after a lengthy 10 hour visit to labor and delivery!!!)
