I have no clue what I’m doing..

I am almost 17w which is still early. I failed my one hour and just got my 3 hour results back. I was told my glucose test returned positive for 1 elevated number. Usually it takes two abnormal values to diagnose gestational diabetes. However, if you have any number >200 then you also meet criteria. Given that my abnormal value was 197. Again, I’m still early in my pregnancy. I have never failed any of my glucose test in my previous pregnancies, nor do I have any family or friends that have gone through this. I honestly don’t know much about it besides what I’ve researched. I feel like my biggest struggle is going to be finding the right meals. This pregnancy I haven’t craved much of anything and most of the time I’m just forcing myself to eat something. What are some good meals, or snacks I can have? I’m completely lost when it comes to what I can and can’t eat. 😬
