I'm constantly having these pains in my lower right stomach, sometimes lower left side.. why?

Need evaluation pls: Causes of recurrent abdominal discomfort as described may be identified by first addressing signs/symptoms so as to localize the organ involved: in women: vaginal discharge or bleeding, alteration in periods, pregnancy risk? Fever, nausea, vomiting, altered stool pattern, blood with stool, tenderness, distension? Painful urination, blood in urine? Recent trauma, herniation? Stressors? Other risks?
