i am 19 years old and i have been experiencing bad ovary pains for over a year now the pain is usually on the left lower side near ovary and in the middle of the lower abdomen, and just resently moving on to the right lower abdomen near the ovary as well, i have seen 3 different doctors, none of which seem to know what the problem is, and i have had a blood test and an abdominal/pelvic ultrasound all came back normal. i bloat all the time, after eating or drinking anything and i am also constipated, my periods have changed in this time aswell and are now quite heavy and the blood is a dark brownish colour. i have done my research on the internet after being sent away from the doctors with no answers, and i found conditions that link to my pains and symptoms, which are endometriosis, cyst's, ovarian cancer, and cervical cancer, i really would appreciate your avidce and suggestiond for what this could be, so that i can get this sorted out.

many thanks for your time it really is much appreciated.
