Hi Cathy:
I believe there are a few of us older moms to younger kids out there. I too have been going through hormonal changes and it is different. I could really use a fan on me 24/7. This could be what is called "perimenopause" causing eractic periods, mood swings, hot flashes, etc. I copied the following from Mayo Clinics website-hope it helps.
"Because this process takes place over years, menopause is commonly divided into the following two stages:
•Perimenopause. This is the time you begin experiencing menopausal signs and symptoms, even though you still menstruate. Your hormone levels rise and fall unevenly, and you may have hot flashes and other symptoms. Perimenopause may last four to five years or longer.
•Postmenopause. Once 12 months have passed since your last period, you've reached menopause. Your ovaries produce much less estrogen and no progesterone, and they don't release eggs. The years that follow are called postmenopause."
