How to Track Your Cycle & Find Your Own Monthly Pattern

Track four things each day and the picture builds itself: whether you are bleeding, your energy, your mood and your sleep. Count from the first day of proper flow rather than from spotting. Three months of that will tell you more than a single blood test can, because a blood test shows one day and a cycle is a pattern.

Learning to track my cycle was the practice that helped me reconnect with my body's rhythms. I do it from time to time, because it can tell me what is actually going on in my body, and there is something quietly empowering about being able to follow rhythms that are constantly changing for me as a woman.

Nobody taught me any of this at school, and I am not alone in that. I sat down with four women I admire for a video conversation about what none of us were taught.

Your body is different every single day

When I first became aware of my ever-changing cycle, something shocked me deeply. My body is different on every single day of the month. Different on day four than she is on day fourteen, and different again by the end of it. Not slightly different either. Different energy, different appetite, different capacity for people.

And it does not repeat itself neatly, month after month. Some cycles you sail through ovulation, some cycles you are flattened by it, and some months you may not ovulate at all. The more I understood about my own cycle, the more empowered I felt, because I could adapt my life around it and go looking for the right support when I needed it.

Why one blood test can only show you one day

Once I understood that my hormones are moving every single day, blood tests started to make more sense to me. A blood test is one day. It is useful and it is real, and it is still a single photograph of something that never stops moving. As I come towards forty, perimenopause is part of my conversation now, and progesterone is one of the things worth keeping an eye on. Tested on one day, in one cycle, it can only show you that day.

There is more detailed testing, the DUTCH test and others like it, which shows you more of the daily rhythm. Even so, it is still that cycle, in that month. Testing every day for a month would run to somewhere around five hundred Australian dollars, roughly three hundred and fifty US, and the following month could look different again.

That is a great deal of money to answer a question your own observation can answer for free, over and over, for as long as you want to keep asking it.

What tracking your cycle gives you

And it is not only temperatures and dates. Sore breasts. A day of feeling weepy for no reason you can name. Constipation that arrives at the same point every month. Written next to the day it happened, all of that stops being random. The more you learn about your cycle, the more you understand why those things turn up when they do, and the more you can do to support yourself through them rather than being surprised every time.

The other thing I would say, from years of sitting in appointments feeling unheard: three months of your own records changes how those conversations go. Walking in with "I think it's been irregular?" is very different to walking in with a chart. Practitioners can work with data. Your temperatures, your cycle lengths, your symptoms written next to the day they happened, all of it gives whoever you are working with something real to look at, and it gives you something to point to when you are being told everything is normal.

It also costs you nothing to begin. A notes app and ten seconds a day is a real start. Later, if you want more detail, there is a thermometer, or a ring or wearable if you already have one. But none of that is where you need to start, and none of it is required. You can begin with a notebook and a pen.

So this is where I would begin. With you, in your own handwriting.

First, the thing that confuses everybody

Day one is the first day of proper bleeding

Not spotting the day before. Not the day your period finishes. The first day of real flow is day one, and everything else counts forward from there.

Your cycle length is from day one of one period to the day before day one of the next. So if your period starts on the third of the month and the next one starts on the first of the following month, that is a twenty nine day cycle.

The twenty eight day cycle is an average, not a standard. Anywhere from around twenty one to thirty five days is generally considered within a normal range for adults, and your own number is allowed to be yours. Cycles also vary from month to month, which is normal and not a sign of anything.

Knowing where I am in the month has been so helpful for me, because I like to eat cyclically and to move cyclically. When I know the day I am ovulating, or that I am still in my follicular phase, I can shape the week around it. What I cook. How hard I train. What I agree to and what I quietly move to next week. None of that is possible without knowing which day you are on, which is why this small piece of counting matters far more than it looks. If you already have my recipe book, this is the part that makes it easy to use. Knowing where you are in the month is what tells you which recipes to reach for this week.

Start tracking your cycle

Truly, this is where to start, and for a lot of women it is where to stop. It is enough on its own.

Every day, note two or three things in whatever you already use. A notes app, a paper diary, the back of your calendar.

• •The date, and whether you are bleeding
• •Your energy, out of five
• •Your mood, in one word
• •Your discharge, in a word: dry, sticky, creamy, wet or stretchy
• •Anything else that stands out: sore breasts, sleep, appetite, digestion, pain, skin, libido, how sociable you feel

That is it. It takes ten seconds.

Do not skip the fourth one because it feels strange to write down. Your cervical mucus changes across the month more reliably than almost anything else you can observe, and a single word a day is enough to start seeing it. There is a whole section on what those changes mean further down.

The magic is not in any single entry, it is in what happens when you have three months of them. Patterns that are invisible day to day become obvious at a glance, and you stop experiencing each hard day as a fresh mystery. It turns "I feel awful sometimes" into "I feel awful on day twenty four", and those are two completely different conversations.

The single most useful thing I ever did for my own health was three months of one-line notes. No device, no app subscription, no protocol. Just enough to stop guessing.

A word about the apps

Apps are convenient, and the good ones are lovely for logging and for seeing your own history laid out. Use one if it helps you keep the habit, just do not mistake the prediction for an observation. Two honest cautions though, sister to sister.

Their predictions are guesses

Most apps predict ovulation by arithmetic, assuming it happens a fixed number of days before your next period and that your next period will arrive on average. If your cycles vary at all, that little coloured window is an estimate dressed up as a fact. It is not observing you, it is doing sums.

The exception is the kind of app built around your waking temperature rather than calendar arithmetic, which is responding to your own body instead of to an average. There is one of those at the end of this post.

Consider what you are handing over

Cycle data is about as personal as data gets. It is worth two minutes reading how a given app handles it, where it is stored, and whether it is sold or shared. Some are much better than others, and a notes app on your own phone hands over nothing at all.

When you want to see ovulation itself

This is where tracking stops being a diary and starts telling you things the calendar cannot. There are two signs, and together they are the basis of the symptothermal method.

Cervical mucus

The most useful sign, the one nobody told us about, and free.

Cervical mucus changes across the cycle in a way you can observe once you know to look. After your period there are often some dry days. Then it becomes creamy or sticky. As you approach ovulation it becomes clearer, wetter and stretchy, most often described as resembling raw egg white. After ovulation it changes again, usually becoming thicker and drier.

Of the two signs, this is the one I would learn first, because those changes show up before you ovulate rather than after. Check when you go to the toilet, note what you see, and give it a couple of cycles before you expect it to make sense.

Basal body temperature

This is my favourite one to analyse and my least favourite one to actually do. It has to be the first thing you do, before you have moved or spoken, and using my head is not what I want from the first minute of my morning. But it is powerful to pick up from time to time, and it does more than most women are told.

Your waking temperature sits slightly lower in the first half of your cycle and rises by a few tenths of a degree after ovulation, staying up through the second half. So a sustained rise tells you that you ovulated, and roughly when. That alone is worth knowing, because ovulation is the event the whole second half of your cycle depends on.

Then there is the part that surprises people. Your temperature usually drops shortly before your period arrives. Once you have watched your own pattern for a few cycles, that drop becomes your heads up, a day or so of warning to clear the diary, cook something warm and move the demanding things to a kinder week.

Over several months the shape of the whole chart becomes the interesting thing. How long your second half runs. Whether the rise is clear or muddy. Whether your temperatures sit low or jump around. None of that is something to diagnose yourself with, and all of it is worth showing to a practitioner you trust.

To read it properly you need to take your temperature immediately on waking, before sitting up, talking, drinking or reaching for your phone, at roughly the same time each day, after at least three hours of solid sleep. A basal thermometer reads to two decimal places, which ordinary ones do not.

I do not do this every month. Waking to a thermometer before I have moved or spoken is the hardest part of all of it for me, and I have made peace with that. What I do instead is pick it up when something feels like it has changed, chart a cycle or two properly, and then have something real to look at, or to hand to a practitioner I am working with. Used that way it is a tool I reach for, not a daily obligation I resent.

Two honest limits. Temperature confirms ovulation only after it has happened. It tells you where you have been rather than where you are going, which is why mucus is the sign to learn first. It is also easily disturbed by a bad night, a late night, alcohol, illness or travel, so expect some noise and read the pattern rather than any single morning.

If you are tracking for contraception

Both of these signs, mucus and temperature, are used to support contraception, either to avoid a pregnancy or to plan for one. They are not always reliable on their own, and learning them properly with someone qualified to teach them makes a real difference to how well they work.

This post is not contraceptive advice. If you are trying to avoid pregnancy right now, or you are trying for one, talk to your doctor about what suits you and your body.

How to actually start tracking your cycle

1. Find day one. It is the next time you bleed properly, or the last time if you remember it.
2. Write one line a day. Energy, mood, anything notable.
3. Do it for three cycles before you look for patterns. One month tells you almost nothing.
4. Add cervical mucus when the daily habit has stuck, not before.
5. Add temperature only if you want the detail, and only if a daily alarm is not going to make you miserable.

Go at whatever pace feels nourishing to you. You can take all five on at once if that is what you want, and you can sit with the first one for months. The habit is the hard part, and everything after it is optional.

Turning your notes into a picture, with the help of AI

If you like using AI to support you, there is a lovely thing you can do once you have a few cycles written down. Hand them to an AI tool and ask it to draw you the shape of your month. Entirely optional, and the notebook works perfectly well on its own.

You do not have to type anything up. A photograph of your notebook page is enough, which is the whole reason I love this. Everything you have scribbled down, read back to you as a picture.

A prompt you can copy

After three or four months you can give it several cycles at once and ask what stays the same and what varies. That is where it becomes interesting: the week your energy reliably drops, the point your temperature usually rises, the symptoms that arrive at the same place every month. Once you can see that, you can plan around your own life instead of being ambushed by it.

This is also the version worth taking to an appointment. Three months of handwritten notes is a lot to hand a doctor or a naturopath who has ten minutes on the clock, and it is easily set aside unread. One clear table and a chart they can take in at a glance is a completely different thing to walk in with, and it tends to get you a completely different conversation.

Four things to hold on to while you do it

• •It can be wrong. It misreads handwriting and it fills gaps with guesses. Always check what it gives you back carefully, line by line, against your own notes before you believe any of it.
• •It is a picture of your notes, not a diagnosis. It cannot tell you what is happening inside your body. Anything that worries you belongs with your doctor, and the notes are what you take in with you.
• •It is not contraception. Nothing an AI tells you about ovulation should ever be used to avoid or achieve a pregnancy.
• •Think about what you upload. Cycle data is about as personal as data gets. Have a look at how the tool you are using stores and uses what you give it, and take your name off the page if you would rather it was not there.

What to do with what you find

Once you can see your own pattern, the rest of it opens up. You will know which fortnight to put the demanding things in and which one to protect. You will know when your energy is about to drop, instead of being ambushed by it every month.

And you will walk into an appointment with three months of records instead of a shrug, which changes that conversation completely. It is one of the more powerful things you can bring anyone you work with.

Please do take it to your doctor or practitioner

Not everything belongs in a notebook, and not everything waits. Please make an appointment, with your doctor or whoever you work with, if you notice any of this:

• •Cycles consistently shorter than about twenty one days, or longer than about thirty five
• •Periods that have stopped
• •Bleeding that is very heavy
• •Severe pain, or pain that stops you doing your ordinary day
• •Breast pain or tenderness that is new, sits on one side, or does not settle once your period arrives
• •Emotions before your period that are more than you can carry, or a week you find yourself dreading every month
• •Being unable to work, study or look after yourself because of your cycle
• •Anything that has changed and you do not know why

Some of these turn out to be nothing much, and that is a good outcome too. What matters is that somebody qualified looks, rather than you carrying it quietly for another decade.

And if you ever find yourself having thoughts of harming yourself, please do not wait for an appointment. In Australia, Lifeline is on 13 11 14, at any hour of any day.

Tracking is how you notice these things. It is not how you treat them.

If you want to go further

Two things I am affiliated with and often point my community towards. Please note that I earn a commission if you buy through either of these links.

Natural Cycles is the temperature app I referred to earlier. It reads your waking temperature rather than doing arithmetic on your calendar, and it is also used as contraception, so everything above about learning the method properly applies to an app just as much as it does to a paper chart.

The advanced DUTCH test through i-screen is the detailed testing I mentioned earlier. A dried urine test, run over a set of samples across a day, arranged and laboratory-processed by i-screen, who are an Australian service, so this one is for you if you are here. Please talk to your doctor or the practitioner you work with about whether it suits your situation, and take the results back to them to interpret.

Where to go next

Now that you know a little about tracking where you are in your cycle, my writing on the four phases of your cycle can really help you know what to do next.

What to eat in your luteal phase covers the second half specifically, which is also the part most of us struggle with.

And if you would like something to cook from once you know where you are, my free guide to balancing your hormones and my recipe book both follow the same rhythm.
