Start charting your cycle today
Understanding your menstrual cycle is one of the most empowering things you can do for your health.
Whether you're trying to conceive, avoid pregnancy, manage symptoms, or simply understand your body better, cycle charting puts that knowledge in your hands.
What Is Cycle Charting?
Cycle charting (also called fertility awareness or menstrual cycle tracking) is the practice of recording daily observations about your body throughout your menstrual-ovulatory cycle.
Rather than just marking when your period starts and ends, charting captures the full hormonal story your body tells each month using biomarkers like temperature shifts, cervical fluid changes, and other physical signs.
By tracking these signs, you can observe hormonal shifts in real time.
It’s important to know that all fertility awareness methods are not created equal, and it’s important to understand the difference if you’re looking for an educator that is right for you.
Fertility Awareness Based Methods (FABMs) is an umbrella term that encompasses anything about tracking your cycle at all, from having a period tracking app on your phone to the Rhythm Method to a symptothermal method.
All FABMs are based on identifying the fertile window (when you can possibly conceive), but some will be more accurate than others.
I teach a symptothermal method that you can learn more about here!
Why Chart Your Cycle?
People chart for many different reasons:
Reproductive choice - whether you're trying to conceive or seeking a non-hormonal method of birth control (when used correctly as part of a Fertility Awareness-Based Method, or FAM)
Symptom awareness - connecting mood changes, energy levels, headaches, or skin flares to specific cycle phases
Medical insight - providing your doctor with detailed data about cycle length, ovulation timing, luteal phase length, and irregularities
General body literacy - simply understanding what's "normal" for you
The Core Signs to Track
1. Basal Body Temperature (BBT)
Your basal body temperature is your body's resting temperature, taken first thing in the morning before you get out of bed or check your phone.
After ovulation, progesterone causes a sustained temperature rise of about 0.2–0.5°C (0.4–1.0°F). This rise, confirmed over three consecutive days, confirms that ovulation has occurred.
What you need:
A basal body thermometer (these are more precise than standard thermometers - look for one that reads to two decimal places)
A relatively consistent wake time (ideally within 30 minutes of that consistent time each day)
At least 3 hours of uninterrupted sleep before taking your temperature
How to take it: Take your temperature at the same time each morning before any movement, eating, or drinking. Write it down!
2. Cervical Fluid (Cervical Mucus)
Your cervical fluid changes dramatically throughout your cycle in response to estrogen and progesterone. Learning to observe it is one of the most powerful fertility signs available to you.
When estrogen is present in the body, we see cervical fluid. That may be creamy, lotion-like, sticky, etc. As we get closer to ovulation, we may see highly estrogenic fluid, which may be slippery, stretchy, watery, or clear. After ovulation, progesterone dries up cervical fluid and we go back to our baseline - the least amount of fluid we see.
This is a deeply personal practice, and everyone’s patterns are unique to them. Learning your unique pattern will take some time - try to be as descriptive as possible when making notes as you’re first learning!
How to observe: Check your cervical fluid each time you use the bathroom. You can observe it on toilet paper, underwear, or by inserting a clean finger. Record what you see and feel using descriptive terms to describe the texture + sensation: dry, sticky, creamy, watery, egg-white, etc.
Optional Signs to Track
Many charters also record:
Cervical position - the cervix rises, softens, and opens around ovulation
Secondary signs - breast tenderness, mid-cycle cramping (mittelschmerz), libido changes, mood, energy, or skin changes
Sleep quality, stress, illness - these affect BBT and are important context for interpreting your chart
How to Record Your Chart
Paper Charts
Printable paper charts are the traditional method and remain highly effective. I offer free printable charts here!
Apps
Several apps are designed with Fertility Awareness-Based Methods in mind. The only app I currently recommend is Read Your Body, which doesn’t see, sell, or do anything with your data.
It’s also highly customizable and doesn’t claim to “predict” when you’re ovulating.
Other fertility apps out there like Flo or Clue that predict your fertile window based on past cycles are not the same as charting. They use averages and algorithms, not your actual daily data. If you're using FAM for birth control, use an app that records your real, daily observations rather than predicting for you.
Getting Started: Your First Week
Day 1 (first day of your bleed):
Note this as Day 1 in your chart
Record flow heaviness, color, texture
Begin taking your temperature each morning
Days 2+ (the rest of your bleed):
Continue recording BBT
Note flow each day
Begin observing and recording cervical fluid observations once bleeding lightens/stops
Post-bleed onwards:
Record BBT, cervical fluid, and any secondary signs daily
Don't skip days - even "nothing to note" is useful data
After your first full cycle: You'll have a baseline picture. It takes about 3–4 cycles to begin recognizing your personal patterns clearly.
Learning to Interpret Your Chart
A single cycle is a data point; a pattern emerges over several months. You may begin to see:
A clear temperature shift
Cervical fluid patterns
Subtle cycle length variations
Mood/symptom patterns
In order to interpret your chart, including confirming ovulation, you’ll need to learn a method/set of rules to interpret your data.
Consider working with a Fertility Awareness Educator, especially if you're using charting as a contraceptive method. Proper instruction significantly improves effectiveness and confidence.
An educator can also help you if you’re experiencing:
Very short luteal phases (fewer than 10 days)
No clear temperature shift (possible anovulatory cycles)
Cycles consistently shorter than 21 or longer than 35 days
Absence of cervical fluid
Spotting between periods
Getting started
You don't need any special equipment to begin today - just a thermometer, something to write with, and curiosity about your own body. Within a few months, you'll have a window into your hormonal health that no algorithm can replicate.
