Kris... I'll be leaving Sat if the weather is permitting. I have a new avatar which I will put up, when I go.

If your doctor will not order a 3hr GTT...that is really odd. (I've had 2 of these in the past, when I was younger).

Ask for a fasting insulin instead. This will show if you are insulin resistant. The higher the insulin level is, the more you know you are on track for diabetic complications. In some ways it is more predictive perhaps than the GTT...esp if your doctor does not feel comfortable interpreting the GTT for reactive hypoglycemia.

If you had any gestational diabetes with the your pregnancies?
That should also be a clue.
