MotherMayEye:It never bothers me. But if you are an active person, at all, then I suggest you get up and walk around while you wait for your blood draw.
The glucose isn't bad for the one hour, you got a lot more of it for the 3 hour, and that did make me feel crappy. I failed both. I was tested early due to a BMI higher than 25 and a family history.
The lab flat out told me I could not get up and walk around. They said if I got up and walked around that the test would be voided and I'd have repeat it. They also told me not to fast prior because that would mess up the results, giving you a false negative when you would've otherwise tested positive. The measured dose of glucose you drink for the one hour is based on a non-fasting level. The reason that it's important to follow their directions exactly is because the goal is not to figure out a way to pass the test, it's to diagnose whether or not you have Gestational Diabetes. It's much better to fail and know about the condition, so that you can start the monitoring and providing the best environment possible for your baby through diet, exercise, and possibly meds. If you pass, but should've actually failed, you could cause problems for yourself and the baby and IMO it's just not worth it. I now know about all the scary crap that can happen in an uncontrolled diabetic pregnancy and I am darn glad I knew about this now so I can take some control over it and hopefully deliver a healthy baby!
