hi... pain abdomen similar to hunger prongs could be due to acid peptic disease/gastritis.. take some antacids and ulcer protective drugs..follow some lifesyle changes like less spicy food, no caffiene/tea, no smoking or alcohol.. do moderate exercises with relaxation techniques like yoga and meditation to reduce stress in day to day life... if it doesnot help see your gastroenterologist for endoscopy and H pylori test..later can be treated for 14 days with H pylori kit.. ovarian cyst if it is functional will disappear within 3 months if not you should see your gynaecologist also..all the very best..
