Hi wildagayn and welcome.
As Ralph says, 47 is very borderline as 48 and over is the usual level for a diabetic diagnosis. So in 'diabetic' terms, you'd be classed as having 'excellent control' which is very positive. But it is pre-diabetic range and unfortunately once we are diagnosed as diabetic, the risks exist for fluctuations and increases. It can be managed (certainly at those levels) with a lower carb/sugar diet and I'm sure you'll soon get into the swing of what suits you to remain stable.
I was diagnosed last Feb and am controlling my levels without meds by home testing and being careful about the amount of carbs (potatoes, pasta, bread, rice, biscuits, cakes) I eat. Don't panic, it's do'able! 🙂
