Can PCOS Cause Headaches And Fatigue With Loss Of Appetite?

ok.. i am a female, aged 23, unmarried, i have Polycystic ovary problems, i have been having headaches in the back of my head and general pain and fatigue in the bosy with loss of appetite..I had periods for 1 month straight with good flow.. i took homeopathy pils to stop it thereafter.. I generally visit a homeopathic for my PCOS problem... ever since I have stopped the periods stopped I get these recurring headaches either in the bck, left or right of my head... it starts sometimes in the afternoon and stays the entire night.. I have been taking METLAF as prescribed by the doctor(6 tablets) but pain still persists.. pain doesnt reduce without this tablet..i visited an eye doctor and a general physician.. they said everything is okay with me... are the headaches because of the PCOS problem..please suggest
