Hello, from the history you have given. ..I would suggest you to do a urine examination , urine routine and urine culture to rule out urinary tract infection
. .....you may have to consult your gynaecologist if urinary tract infection is ruled out....missing a period or delayed period could be either due to pregnancy
, even in the presence of underlying disorders like thyroid
etc.. A diagnosis can be made only after a detail history and an examination by your doctor. .....hope i was helpful to you. .....
