I am irregular with my periods to where I only get 2-3 a year, and my last one was on Oct.22,2008,yet my home pregnancy test came back negative and both sides under my rib cage hurt my lower back, and my lower stomach area. I am scared and not sure what to do at this point. some advice would be gratefully appreciated.
Lower abdominal pain and lower back pain may indicate infections or tumors of the kidney, bladder, and/or reproductive system. I advise that you see your doctor as soon as possible.
