Lab numbers Fluctuat: The blood test number tend to fluctuate from one time to other. So I do not think your sugars or A1C are any worse now than they were in Jan 2016. As long as your Fasting blood sugar is staying under 100, you are safe. But in the meantime, continue your increased physical activity daily. That will keep you healthy. Recheck your sugar and A1c in 6 months from now and perhaps once yearly thereafter.

Glucose exposure: A1c level depends on the average glucose exposure and thus may vary with time. The rising level however suggests that you are likey pre-diabetic and thus needs to be monitored. There is study showing that about 11% of prediabetic becomes diabetic annualy. Consider exercising regularly and modify your diet. Do talk to your doctor about this also
