text: Uterine fibroids, adenomyosis and a hormone imbalance are 3 major causes of heavy menstrual bleeding.  Given your cramping, I would suspect the first two.  You are bleeding far too much and it does need to be addressed in order to protect your health.  Treatments include medical and surgical options, like oral contraceptives, endometrial ablation and/or surgical treatment of the fibroids or adenomyosis (if they prove to be the cause).  The cure for adenomyosis is a hysterectomy, but sometimes endometrial ablation can help some women with the disorder.  A local women's clinic, Planned Parenthood or similar organization should be able to help you with diagnosis and treatment on a sliding scale basis if lack of insurance is an issue.  Good luck!
