What Are The Symptoms Of Menopause?

For the last 3/4 weeks had uncontrollable shivering and then sweat running down my face and head. I am 57 years of age. A week ago I had a full lab works done and it came back ok except for my red or white blood count was on the low side (something about bruising easily and to be careful when I cut myself). I have an under active thyroid, high blood pressure and fibromyalgia. I was diagnosed being under active and post menstrual at the age of 43 and have taken levothyroxine and Hrt. I stopped taking the Hrt and went onto dulocatine. I stopped taking the dulocatine about 3 months ago and started having occasional hot flushes and now this. Do you think it could still be menopausal -to this extreme degree at my age?
