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!

Amazing information for ALL women!

I cannot believe we are not taught this information about our bodies. I’ve learned SO much from this book and am already applying it in my life (preconception health, using FAM to prevent pregnancy instead of dangerous pills, and then to conceive baby #2 when we are ready). I used some of these concepts in tracking to conceive our daughter and we conceived on the first try - it’s amazing what knowing your body does for your health.

My top recommendation to women!

I've been a childbirth educator and birth doula since 10 years and am beyond thrilled to find this resource for my clients. This book is a must-read for anyone who ovulates/menstruates!!! If that's you, please please read this book. Whether you're trying not to conceive, trying to conceive, or just wanting to increase body awareness and wisdom so you can become your own best health detective, this is the BEST book for any and all of that.

I feel ready

Ready to ditch HCs! I'm already a listener of Lisa's podcast so I knew somewhat of what I was in for for this book, but now I feel even more fully equipped with the resources I need to overcome painful periods and start using FAM as a contraceptive.

Wish I had this book years ago!

This book. I cannot say good enough things. Lisa does a simply incredible job and presenting the evidence-based science behind fertility, women’s reproductive health, hormonal contraception, and menstruation. She does so in a way that is captivating and easily digestible. I wish I had this book years ago, and perhaps I would have reconsidered hormonal contraception as a young teen. Incredible work!

If you have a uterus, you must read this book!

I cannot recommend this book highly enough to literally anyone with a uterus. Whether you are looking to get pregnant, avoid pregnancy, or simply optimize your health, Lisa walks you through everything you need to know in evidence-based, science back, terms but explained so you don’t need a medical degree to understand. Her advice is thorough and actionable. Highly highly highly recommend!

Why isn’t this taught in schools? A brief overview of all things period related. So much I never knew.

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.
