yes you must definetly go and do you FBS/PPBS and HBA1C
test done as the symptoms you have mentioned are classic symptoms of diabetes
if your BMI is above 25-26,or having any menstrual abnormalities, get yourself screened for PCOD.
my advise to you is to start lifestyle modification and exercise from now onwards....
