I had GD with my second, and tested normal after she came. This time around I had a glucose test with the blood work they do on the first visit- and the sugars were normal. I think you would feel icky if you had high blood sugar. You would pee a lot, sweat a lot, feel light headed. I know it sounds a little like being pregnant- but I still think you would feel it.
