I failed the one hour too. I don't know why - I didn't eat before it (I know that can give you elevated blood sugar levels), and I was really good with the foods that I ate the few days beforehand. So I was pretty sure I would fail the 3 hr. Anyway, I ended up passing the 3 hr just fine!! It made me terribly sick though, I was sick for the rest of the day and was very off the few days following it. Good luck!
I failed the 1 hour but then had a 2 hour test (in Canada) and passed that. :) I have heard of this happening to many other ppl as well. I'll keep my fingers crossed for you! :)
I failed both 1 hour and 3 hour and now dealing with GD. Mot ladies who fail 1 hour test do pass the 3 hour test though. I hope it's your case.
I am so sorry you have to take the 3 hour test, it's not pleasant!!!
