All my life I've lived in books.
I realize now that from the time I was a child, the voices I heard in books were as authentic to me as the voices from the people around me. It still feels that way.
Long before I embarked on this menopausal journey, I discovered a book called The Wise Wound. If you have not encountered this book before, I urge you to track it down and read at least a chapter or two. When I read it, in my twenties, it both affirmed things that I had always felt to be true deep within my body, and enabled me to understand the cycles of my body in a whole new way. I hope its perspective enabled me to offer my daughters an even more reasonable understanding of their periods than my mother had offered me. (And my mother, Goddess bless her, as a nurse, did a great job.)
So when I began to feel changes in the mostly regular tides of my body, I turned to books for wisdom. These listed below are just a few of the ones I found to be the most helpful - I welcome suggestions from you for more:
Susun Weed, The New Menopausal Years
Paula M. Reeves, Phd, Women's Intuition
Diann Sylvan, The Body Sacred
Carol L. McClelland Phd, Seasons of Change
Elizabeth Owens, Women Celebrating Life
