Fasting BGs are only one measure. Your HbA1c is a perhaps better measure of your overall control as it gives you an average BG picture, and is what your doctor would use to decide if you need meds. Don't be over concerned though; metformin is the normal first line drug and lots that are denied it would like to be on it. It only has a small effect on BGs but is a good preventative against cardio problems in the future, a common complication of diabetes. It doesn't cause the pancreas to work harder, doesn't induce hypos and has no real downside at all. It can cause some tummy upsets initially in some people which normally wear off, but if not there's a slow release version that doesn't do this. It's a very safe drug that's been around for decades.
