I have endometriosis, I just had two very heavy periods only 10 days apart, I have been feeling lightheaded, sick and dizzy since my last period, which ended about 2/3 days ago. I am urinating far more than usual, not drinking more fluid though it s extremely bright yellow. I have pain and discomfort in my lower stomach. This feels different to the usual pain and discomfort associated with the endometriosis. Any advice please?
