A revolutionary, must-have approach to tracking and charting your hormonal cycles—a necessary guide in the pursuit of understanding your own body

Millions of people track their cycles on apps because it's a convenient way to know when your next period is likely coming. But those apps are also tracking your data, sometimes in ways that are not legal or consensual. And they don’t go deep enough. What's worse, they're also leaving users vulnerable to surprisingly inaccurate fertility predictions, with some studies estimating efficacy at about 20 percent for correctly predicting ovulation.
Written by a midwife and a clinical sex therapist, The Cycle Book is the solution. It’s the customizable book they dreamed up because they needed it so desperately—for their patients, for their friends, for themselves. Complete with journal prompts and a full year’s worth of beautiful, simple-to-use cycle tracking forms, this is daily charting made easy.
When you learn how to track your cycles, you are learning to:

• expand the pleasure in your life

• manage and prevent pain

• regulate your moods and emotions

• chart the ups and downs of a relationship

• understand your period

• ease the symptoms of endometriosis, anxiety, IBS, or perimenopause

Cycle tracking can even be the missing link to getting a chronic illness diagnosis or the final piece of the puzzle in understanding your mental health.
Menstruation is vastly understudied and has not been given its due by science and culture. We’ve been done wrong! Now, there's a better way. The powerful tool of tracking is so valuable that everyone can learn from it. The Cycle Book is an education. You decide what to track, and Laura and Morgan will help you step-by-step as you take back control over your cycles—and your life.
