I had an endometrial ablation in 2007 due to dangerous bleeding so I haven't had a period since then but I still cycle. I have to find out these things from blood tests. The last one said that I was not yet post-menopausal which I had assumed. I do have lots of mood issues but always have so I'm not sure about that. I do occasionally break out into a sweat but not always at night. The one thing I'm noticing is water retention and changes in body composition. Don't really know, but read somewhere that shifts in hormones can be a cause.
