I have been having strange cramps in my lower right abdomen. What could it be? I am a female and have had negative pregnancy tests.

GI, GYN; C ur Doc. Don't know your age, menstrual/pregnancy history. Things to check for: duration of symptoms, fever, timing related to meals, nighttime, urinary complaints, bowel changes, appetite changes, weight loss, nausea, bleeding; last md was when? Age related re: colon polyps, ca, ovarian cysts, etc. May be gas but... Acute symptoms- maybe infection, inflammatory bowel or early appendicitis. C ur doc now.
