It’s 100g of sugar on an empty stomach. It won’t harm you, but it’s really uncomfortable because pregnant women don’t do well with starving themselves then pigging out on sugar! So don’t worry too much, I know lots of women feel horrible after this test and some even throw up or pass out. It doesn’t bother other women, go figure! Next time (if there was such a thing) pack something to eat right in your purse so you don’t have to drive home like that.

I hope you’re rested up now, and congrats on the normal results.

I was that way (shaky, dizzy, nearly passing out) after the hour was up. I even got sick in the waiting room. My blood sugar was too low, not high, and they didn’t have me do the 3 hour test.
No, I don’t have gestational diabetes, just low blood sugar (which I’ve had to go to the ER for, since being pregnant).
