I can relate with your worries. I had Hypoglycemia symptoms most of my adult life, and when I was pregnant with my first child, I had that test with similar results. I have a strong family history also, my grandmother and father, and my uncle on my mom's side all had diabetes. Last year, a month after I turned 55, I "flipped" (as I was told) and am now full-blown diabetic. Unlike you, I had all the symptoms... thirst, frequent urination and sudden weight loss. I started on meds and diet, etc. and was very stable for a year. Now I'm having unstable sugar readings and symptoms of neuropathy (mostly numbness in my hands). It's much better to get diagnosed and get treating it before it gets worse IF that's what's going on. Let us know what you find out.
I would have thought it would take a long time too, but not in my case... all this happened in a year. I'm guessing you're a LOT younger than me if you're trying to get pregnant . I've never heard that being diabetic would interfere with fertility, but you could look online and see.. I'm sure someone else will know more about that. I know all about pre-testing worries and anxiety, as I've been through it many times. One thing I can say about a diabetes diagnoses is that there is a LOT you can do to help keep it under control. I know it's not much comfort to say not to worry, but just know I'm thinking of you and everyone here will be here to help you no matter how the tests turn out.
