We're all different. In my case, I have convinced myself that my fasting reading was useless.
I've done this by simply taking readings at one hour intervals in the morning (without eating).
What I found was that a good reading at, say, 7.30am turned into a rubbish reading at, say, 10.00am.
So the longer I lay in bed, the higher my readings.
Now that I'm semi retired, I don't get up at the same time every day so I've stopped taking fasting readings.
When I was taking them, they were higher than I'd like at around 7.5 to 8.5 or higher, even though my HbA1c (which I consider the key indicator) has come down to a really good level for me (39).
I got far more consistent readings with the 2 hour testing regime, consistently in the high sevens.
Your doctor will almost certainly be guided by you HbA1c reading which, in rough terms, gives him a three month average reading.
You didn't say what your reading was last year, but if you haven't amended your diet and you aren't on any medication, why would you expect it to be different? I suspect that you have been more careful with your diet than you think and that will hopefully show in your result. I had many lapses in my eating regime (still have) but still managed to get my readings down. Unfortunately, it's not an exact science and no two people seem to be exactly the same.
I wish you all the best with your review.
