Kindly do not stop medicine. Because of medicine, it is normal. You can reduce the dose to 75 mcg first .. and continue the same for 3 months and do the same
thyroid profile again after 3 months.( Earliest you can repeat after 1 month of taking 75 mcg) .. if the report remains in the same range on minimal dosage then we can consider stopping it.. (do not stop after 75 mcg as well, we need to gradually lower the dosage)
Next Steps
Consult if you have any symptoms, weight gain/weight loss, swelling, heart rate abnormalities etc.
