Oh and jumped back just to add about "choosing not to spike your sugar."
That poster obviously knows NOTHING about GD.
I had it with DD#1 and you know what could cause a sugar spike (as I was on an ultra-restrictive diet)--?? Cream of wheat. Or a sandwich with half the roll removed. Or a burrito. Milk in your cereal.
With GD I couldn't have milk at all in the morning, and had to limit my fruit intake also. I had to eat protein anytime I ate anything at all to balance it out. It's absolutely impossible to "not spike your sugar" if you are just eating normally and not taking the time of day/mixing up what you eat precautions as prescribed by a doctor/nutritionist and careful monitoring. Even when I was meticulously following the diet, I still had a few spikes (caused by the things above, except the cereal as that was forbidden except for a late evening snack), and they fell within the guidelines of "okay foods." Just my insulin levels were totally out of whack thanks to the placenta.
So, PLEASE take the test. I was carefully monitored and had no complications, but I did start having a high level of amniotic fluid (which they monitored) and was at risk for a cesarian because of having GD. It all worked out because I knew I had it, controlled it, and was monitored for it.
As to the "sugary drink," they have it without dye. The one I took this week was clear. Still nasty, though. It'd be nice if it was just juice but juice isn't high enough in sugars, and also, that's fructose not glucose.
