I was put on Depot Lupron (hormonal chemical theropy) to treat endometriosis 3 years ago. Then 1 year of Depo Prevara. I got off these meds to regular birth control, and have been on that for about 2 years now. Since being on the regular bc, I have been experiencing clotty periods. Not just clots in the blood, my ENTIRE period is clots. Some are larger than a quarter in size and range in color from pale pink to almost brownish. Does anyone have any suggestions? I have been tested for anemia and other blood disorders, everything clear. I have history of hormone sensative cancer in the family, should I be worried?
