Difficult to say without examination.
Ruling out GYN causes with a pelvic exam, pelvic CT, and transvaginal ultrasound can be considered.
GI causes can include inflammatory bowel disease, irritable bowel disease, or organ disease like appendicitis. An endoscopy or abdominal/pelvic CT scan can help.
If these options are non-revealing, an orthopedic referral and imaging the hip can be considered.
These options can be discussed with your personal physician.
Followup with your personal physician is essential.
