Welcome to the forum MGF and well done to both you and your husband for making such a great start. Don’t panic about the raised blood sugar, this is common and will eventually drop again. Like you, I was not diabetic or pre-diabetic. However, I decided to get a monitor to see where I was and to track my levels, as part of the BSD exercise. My fasting level started out around the 5.2-5.4 mark, this raised to 6.1-6.3, but then dropped again and now runs at 4.8 to 5 most of the time, although to be fair, I only occasionally check these days, as I have no health reason to worry about BS levels.
If you use the search box at the top right of the page, you will find that many have identified this phenomenon, but be assured it will come right.
Keep doing what you are doing and you will both reap health benefits.
