Progesterone only

I wasn't sure which flair to use. I'm 20 years in remission from Breast Cancer. I was ER + PR - . I'm post menopausal and up until 5 years doing ok. The past 5 years have been hell with increasing exhaustion and sleep deprecation. After 5 "specialists" in HRT none were willing to consider me for anything... risk wise understandable. I don't want estrodial; but not opposed to testosterone and or progesterone. My question is :: Has anyone taken just progesterone alone and if so did you get any relief from it alone or not ? TIA ❤️
