Hello Lucky Singh
Usually we advice the diabetic patients to get there fasting sugar checked once in 15 days. But if you start a new medicine or alter the medication than we have to check the FBS after 3 days to see the effect of medicine. So you can now check the blood sugar level and consult your doctor.
In addition to this I also advice to check your HbA1C
once in 3 month. It shows the blood sugar status of previous 12 weeks. This is much accurate test to check control on sugar level.
Please follow all the precautions advised in diabetic patients. As per your query its good that you are following them.
Hope you got your answer.
