Has anyone here failed the 1hour glucose test and had to go back for the 3 hour test? I was a borderline diabetic for the last 11/2 years but my last test was great. Now im 10the weeks pregnant and i failed. Not gonna lie im kinda nervous, my dad is a diabetic. But here is my question, can you drink water during the fasting time? I was a little in shock when the doc called and i only remember her saying no food and im thirsty since i cant sleep from stress lol
