I went through a similar situation - too much progesterone.
No natural progesterone products helped!
What helped was a product from Standard Process Lab (Wisconsin). A lot of their products (all natural!) treat glandular problems. If your body does not produce enough progesterone, the reason for this may be some other little gland that is affecting your ovaries and the production of estrogen and progesterone.
The product that helped me is called "Ovex". It helps very well with excessive menstrual bleeding at any age. All it takes is 3 small tablets a day and it helps within 2-4 days to stop the bleeding. Definitely, beats any chemical product made from a pregnant mare's urine that doctors like to prescribe in such cases.
To better diagnose a patient, the company has a 3-page questionnaire that you fill out and it helps to single out your problems. Definitely worth trying!
