Causes in that area can include diverticulitis, irritable bowel syndrome, inflammatory bowel syndrome, a colon mass, gynocologic conditions such as ovarian disorders, endometriosis, and urologic conditons including bladder disorders.
Tests for further evaluation would include an abdominal CT scan, urinalysis, or possible colonoscopy - which can evaluate for the GI causes and rule out any genitourinary infections. If negative, you may then consider a transvaginal ultrasound, which would be a sensitive test to evaluate the ovaries.
I would suggest further evaluation with a gastroenterologist or gynocologist.
Followup with your personal physician is essential.
