Hi Queen Vee.
We are at a very similar point in this journey. I have my blood test next week but have been monitoring with a codefree monitor for a month now since a spot check revealed higher blood glucose that was normal for me.
I had gestational diabetes 4 years ago when pregnant and have tested my bloods once every 2-3 months since. I had been feeling rubbish since September (exhausted) and had been gaining weight fast although eating "properly". So it wasn't a surprise when my home readings were high.
I instantly reverted to the low carb diet that was recommended to me by the specialist while pregnant and within 3 days I felt normal again and my post meals readings were back down to below 6. But like you my morning readings were higher than seemed logical (around 6.4).
So I read the bits recommended above and then added overnight fasting and 1 hrs moderate daily exercise into my routine alongside the low carb. (I use an aerobics step while watching an hours tv as a guilty pleasure that also hits the daily exercise needs)
I am now 3.5 weeks in and I am getting morning blood readings below 6 at least 4 times a week. I am finding that, for me, that the following external factors also affect the morning readings: hormonal cycle, amount of sleep, having a cold.
Good luck on your journey. I am so very grateful for this site and its forum for giving people the information to make informed choices about their own health and also to address the guilt surrounding diabetes.
