How about natural progesterone? There is a book called "what your doctor won't tell you about perimenapause" where a doctor john lee talks about natural progesterone and how the bleeding is caused by an imbalance of estrogen and progesterone. I Have used it and I find it does help. You can look up Emetria on "Amazon" and see the life changing reviews. It is a creme that you just rub on. It goes into your blood stream via the skin.
