I failed my 1 HR test (170) at 26 weeks and went back 1 week later for the 3 hour. I was super concerned (type 1 diabetes runs in my family) after I failed the 1hr, so I went to CVS and bought their brand glucometer because I didn't know how much I should invest in a meter and strips on the chance it was a false positive. It's not as accurate as the name brands (can be 2-5 points off and gives REALLY high readings if you don't fill the strip all the way) but it was a comfort for me to know my general blood sugar range (name brand test strips are HUNDREDS of dollars but can be covered by insurance after the 3gr test and a script from your dr). I ate like normal for the first day, testing as soon as I woke up and then 1hr after each meal. I was normal (78) when I woke up, but shot to 133 after breakfast of Greek yogurt and berries (I blame coffee creamer). I stayed in the 120s all day, which is considered too high. So, the next day I cut all carbs and sugar (no rice, pasta, beans, lentils, fruit [except berries], corn, potatoes, bread, peas, or condiments [other than mustard, balsamic vinegar, and mayo]). My numbers lowered dramatically and I've been in the 80s and 90s since (I started testing 3 weeks ago). I ended up failing my 3hr test, and have my first Drs appointment with a specialist on Tuesday. I'm not sure if this helps you, but I do recommend buying the store brand meter and testing. See which foods make your blood sugar go up, and then avoid them. I also had my husband eat and test with me so I knew how much higher I was than "normal" readings. We went to Chipotle and got the same exact thing (burrito bowl with chicken) and an hour later he was at 100 and I was 117. 2 hours later he was 86 and I was 119. Anyway, that's my advice & experience. Good luck!!!!!
