3hour test second pregnancy

Nicole

I had GD my first pregnancy. I was diet controlled. I failed the one hour this time with a 146 and decided to do the 3 hour. I checked my fasting numbers in the car right before I walked in and it was 71. Well they did the fasting blood draw a few minutes later and it was 110 on their meter. 😫🤷‍♀️ is my meter bad? I don’t understand how it is so off. I’ve had it a couple years but only actually used it a few months. I just feel like I’m wasting my time right now if all my next number is high. I was borderline last pregnancy so I guess it’s just wishful thinking. I fasted for a little over 12 hours this time. I just don’t want to sit for 2 more hours if the next number is high and I’m going to be diagnosed regardless especially since I’m anemic and feel like passing out. 😳 any thoughts?
