Hi, Welcome to Health care magic forum.
You have stopped taking birth control pills 15 days, ago, and sick since 2 days.
It appears to be due to some infection, may be fever
due to urinary tract infection
I advise you to consult a physician for diagnosis and treatment.
I usually prescribe to my patient with such symptoms cifixime, paracetamol
, and ranitidine
Wishing for a quick and complete recovery. Thank you.
