I feel intense cramping in lower abdomen. What doctor should I see?

Lower belly cramps. Causes of recurrent lower abdominal discomfort may be identified by first addressing accompanying signs/symptoms so as to localize the organ involved: 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, herniations? Age? Gender? Risk factors?
