The goal of this multicenter prospective observational study and registry of U.S. adolescents and young adults with heritable bleeding disorders is to determine the bleeding outcomes, satisfaction, hemostatic parameter changes, and patient reported quality of life after 6 months of use of either of two commonly used hormonal treatments for menstrual suppression - levonorgestrel intrauterine device (LNG-IUD) and norethindrone acetate (NETA). Under this application the study will compare the two treatments and compare outcomes after LNG-IUD treatment results to a control group without a bleeding disorder, with the goal of determining the benefits and expected outcomes of these treatment options for this population.
