Thank you!!!

I chose this book for the vast and researched information following listening to Lisa’s Fertility Fridays podcast. It did not disappoint. It filled in the gaps I needed to understand my body and reduced the fear about being older trying to conceive. Between the podcast and the book it’s been 2.5 months eating healthy (even liver 😉) and today I got my first positive pregnancy test. I know it’s early but now I believe it’s possible for me to become pregnant where before I doubted it. This book is for people who are willing to listen to the research, track signs and symptoms, and change their eating habits. Again, thank you!

Empowering, engaging, life-changing

Thank you Lisa Hendrickson-Jack, thank you, thank you, thank you. The dedication to research based knowledge conveys women have been denied vital education. This book provides women with accessible methods of redefining liberation both mentally and physically through fertility awareness.

A book every girl and woman should read

Lisa managed to digest the last century of material on fertility and the “period” and it is the best knowledge a young or any woman can have. The fertility awareness and all other insights in the book, like how to identify health problems through your chart, should be mainstream- every parent, school and gp should know about it. She bravely challenges the misconception about the safety of the pill, the gaslighting of women by medical practitioners. The book is like a bible on fertility health. It is a must have for any women trying to avoid or achieve pregnancy, but also to be... healthy! I salute Lisa for her determination to change the field of women care and empower women to know and listen to their body. The Fertility Friday podcast brought to us this incredible book that should be translated in all languages.

Every woman needs to read this!

I had so many ‘ah ha!’ Moments while reading. There were also moments that made me angry - but not at the book, at the fact that I (as a 30 year old woman) didn’t already know.
I have learned so much and will be listening to it again when I need a refresher on the fertility side of things.

My advice? Read the first half and skip the second.

This book begins with some useful information about women’s reproductive systems, menstrual cycles and how they are affected by hormonal contraceptives, and a basic overview of the fertility awareness method. Following this, it provides a lot of questionable life and health advice based on personal opinion and pseudoscience. The information in the second half of the book made me question the validity of the medical knowledge and research presented in the first half of the book. Despite its controversial content, the author’s narration makes this book an easy read. In summary, this book offers some interesting ideas for women to think about (and research further), but I would not recommend it to others.
