Lynn, did the GTT return your insulin levels as well or just glucose? My glucose levels are perfect, but my insulin levels were 5 times higher than they should be.

If your insulin levels are normal, and you are losing weight with the current diet and exercise regime, then you are probably ok without metformin. You won't need it, but that's also not to sat you won't benefit from it. It is something that you will need to discuss with your doctor.
