Have been following the cycle of this book for almost 3 months
Reviewed in the United States on February 22, 2020
My previously-irregular cycle has synced up to the exact 27-day-cycle as described by the book for both of the last two months. No one could be more surprised by this than I.
Given that my cycles prior to following this book were 30, 25, 35, 28, and 28 days respectively, I really do consider it near-miraculous that I have apparently synced with this book for almost the third months running. Sounds voo-doo, I know. Hope it lasts. Love it.
