Natural Birth Control
Learn how to work with your menstrual cycle so you can choose if or when you get pregnant without relying on a dismissive doctor's advice or birth control options that make you feel crazy
You have the option of natural birth control without the downsides the world has taught you are normal
You don't take "just because" as an answer in any other part of your life - so why is your reproductive health the one area where you’ve been handed a single option and told to be grateful for it?
Maybe you've sat in an appointment, described what your body was doing, and watched a doctor's eyes glaze over before they reached for the prescription pad.
Maybe you tried the pill, the IUD, the implant - and when you felt foggy, flat, or just totally off, no one could tell you why or what your other options even were.
Or maybe nothing dramatic happened at all. You’ve just presumed “hormones or nothing” is your only option because no one ever taught you that your body is communicating with you every single day, and you can learn how to read it.
You've spent over a decade having a cycle without ever learning its language.
You need the education you should have gotten at your first period - and never did.

Natural Birth Control is a 6-week online program that helps analytically-minded women and menstruators learn to read their body's fertility signs with contraceptive-grade confidence
Cycle charting is not a lifestyle. It’s a learnable skill.
You don't want to rebuild your fridge, buy a shelf of supplements, or adopt a new identity. You want a method that you can learn, apply, and trust, the same way you'd trust any other well-built system.
Go from not understanding your body to trusting it (with real, trackable data to back that trust)
In 6 weeks you’ll learn to
-
Know exactly when you’re fertile (without an app, algorithm, or guess)
-
Understand why you feel the way you do throughout your cycle, whether it’s energy crashes, creativity surges, mood swings… and how you might support it
-
Make informed choices about conception or contraception based on YOUR data, not corporate interests
-
Recognize when something’s actually wrong and advocate for yourself with doctors who had only a few hours of menstrual cycle education
Without guessing, without apps doing the thinking for you, and without turning cycle tracking into a part-time job - so you can make reproductive decisions from real data instead of fear or default medical options

“Working with Kate to understand and map my cycle gave me an education I didn't know I was missing… Observing my body's patterns through cycle charting has felt like uncovering the magic that's been happening this whole time.”
-
“This class changed my relationship to my body fundamentally - instead of being frustrated by changes in my cycle or symptoms, I now understand what my body is trying to tell me, what it needs for support, and why these changes might be happening.”
-
“This program was one of the most illuminating, life-changing experiences of my adult life, and I cannot believe I went most of my life without understanding the basic tenets of my hormonal and reproductive cycles.”
Certified Fertility Awareness Educator
Hi! I’m Kate. I am a total cycle nerd, and I have made it my mission to teach others this life-changing skill.
I started Earth Body to bring body literacy to as many people as possible. I have been lucky enough to train in a variety of fields that honor and support cyclical wisdom, and I wanted to put practitioners from different fields in conversation in dynamic ways.
I hope this community sparks inspiration and dialogue between individuals and practices all over the world.
I found this practice in my 20s and was seeking a non-hormonal contraception option.
I was already interested in herbalism and bodywork - but I had never considered that my cycle (which was often painful and taboo) would be a renewal resource in my life.
Not only has this practice been my primary birth control for 8+ years, but it also empowered me to seek out a fibroids diagnosis and get additional support.
Now, I know exactly where I am in my cycle and how to adjust my lifestyle accordingly with clarity and confidence.

FAQs

According to the World Health Organization, the symptothermal method (the method I teach!) is highly effective when properly learned and applied. Other, simpler cycle-tracking methods have success rates close to those of condoms.
There are many variables that will impact a FAM’s success, including:
accurate application of the method
quality education
motivation
supportive community/partners
Other recent studies include this 2007 study from Germany that found the FAM method was 99.4-99.6% effective in preventing pregnancy when used perfectly. Taking into account user effectiveness (human error, etc.), its efficacy rates at 98.2%.

Ideally, folks who join the class series are off hormonal contraception before we starting working together so they can take part in the full practice with biomarker checks.
However, many clients take this class in anticipation of coming off hormonal birth control.
Please reach out if you are want to join and have any questions!
-
If you know the rules for contraception, you’ll have a basic understanding of how to chart to conceive. But if you are looking to prepare for conception, I suggest my Charting to Conceive course!
