My lower left side of my stomach hurts. help?

May be GYN related: Most frequently left lower quadrant abdominal pain in a young female is caused by gyn related issues (e.g. Ruptured ovarian cyst). Less commonly, at this age, a condition called diverticulitis (inflammation of colon diverticula) may cause similar pain. Rarely appendicitis may present with pain on the left side instead of the right. Other causes are related to urinary tract.
