Hi Fuzzy.
CONGRATULATIONS! I just got to go through the emotional roller coaster of pregnancy. There are never ending things to worry about. Fortunately, since this was my third pregnancy, I had previous experience to fall back on.
Guess what -
you are doing great. Perfection is not required. Whenever I was questioned about my diet, I simply stated that I was working with a dietician and people would back off.
You don't have to take the glucose challenge test. Everything that they tell you is mandatory is actually optional. Medical professionals are simply service providers, and you can decline any test or procedure they recommend. I'm notorious for "forgetting" to set appointments for that kind of stuff, or calling and cancelling. That being said, I think you'll pass. Also, if you have gestational diabetes, you probably want to address that because it can cause complications for you and baby.
Should you decide to take the test, if for some reason you don't pass, you get a follow up test that is more in depth to confirm the diagnosis. Also, you could get a glucometer and test yourself at home in advance of the test to get an idea of how you are doing, but, again, less than 1 in 10 pregnant women have gestational diabetes, and it's linked to obesity. You stated that you were a healthy weight to start, so unless something crazy has happened in the last four months, you're fine.
My midwife had me do a week of food journal and fasting blood sugar in place of the glucose challenge test. It was interesting to see how food choices impacted my blood sugar. As long as I ate on plan, my blood sugar was fine, but if I ate crap I was borderline.
To prepare for the lest, I would suggest having a really good 5+ days on plan. Keeping the fats low (absolutely no oil or animals, limited rich foods) can really help, since intramyocellular lipids (fat in the cells) causes the insulin resistance, which results in the higher blood sugar.
The diet to treat type 2 diabetes is the same as gestational diabetes, so if for some reason you did get the diagnosis, you would just follow the maximum weight loss diet and everything would be fine. At that point I would recommend booking a call with Jeff to make sure your diet is on point. Or, there is a dietician that works at PCRM who specializes in plant-based pregnancies who would be knowledgeable.
If you have have any questions, feel free to send me a PM. I'm on the forums all the time right now while I nurse the baby (she's two months tomorrow!).
Also, here is my list of pregnancy and children related links. Nothing relating specifically to gestational diabetes, though, they are worth a read.
