I had to do the 2 hr test with each pg. My ob routinely does those first instead of the other one. I felt so sick the first time with not eating that I asked not to do it the second time, but my results were high the first time so she wanted me to do it. I wasn't as bad the second time. I think my results were high the first time as I hadn't eaten the carb diet (they only told me about it when I turned up for the test).

Also, I didn't need a urine sample either time - my ob checks urine each visit and I think she specified on the order form no urine necessary. So maybe check first whether you'll need that.

I took something to eat with me so I could eat as soon as it was all over. I think asking pg women to fast is a form of torture.
