Hello,
For your symptoms, endometriosis should be ruled out. Symptoms of endometriosis include pelvic
pain(usually before
menstruation but sometimes during intercourse,urination or defecation), sometimes diarrhea or constipation,irregular or heavy menstrual bleeding,sometimes blood in the urine and inability to conceive.
Although ultrasound is useful in diagnosing endometriosis, but still cannot definitively diagnose endometriosis.
