I am bleeding twice a month for 1 year and 3 months now, and the bleeding last for 8-10 days and the second one last as far as 23 days. My female organs arent normal i have only one kidney, two uterus and two cervix, plus i have myoma uteri... the bleeding has an occasional bearable but disturbing pain,. i have so many check ups now but i think they're just experementing on me... please help
