You should get the possibilities of endometriosis and adenomyosis ruled out from your gynecologist. The typical signs of adenomyosis are prolonged, heavy bleeding during your periods or severe cramping. 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.Laproscopy is the only accurate way of diagnosing endometriosis. Get it evaluated from a gynecologist to confirm the diagnosis.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
