There is no set age of when a woman will go through perimenopause or menopause because I think that all woman are different. I am 43 years old and have been suffering with hot flashes, night sweats, mood swings, and changes in my cycle for the past 6 years. When I first started with these symptoms I went to my doctor and of course they told me I was too young to be experiencing perimenopause. Well my body doesn't think its too young. I've struggled with it until the past 6 months when I found an all natural balancing creme. It has helped tremendously. I can't say that it has 100% taken all my symptoms away but it has worked wonders for me.
