If you’ve ever wiped and wondered, wtf?!, you’re not alone. Cervical mucus can feel mysterious, confusing, and, let’s be honest, a little weird at first.

Mucus is actually a powerful sign of your fertility, and understanding it can completely change the way you relate to your cycle. Whether you’re trying to avoid pregnancy or just want to feel more in tune with your body, learning how to track your cervical mucus is one of the most valuable skills you can develop.

Let’s break down what your mucus is telling you, and how to start making sense of it. I’m going to deep-dive into the different types of cervical mucus as well as how to check for mucus!

Making cervical mucus make sense is one thing. Knowing what it’s telling you about your fertile window is another. You can keep learning about FAM and charting ovulation here.

why is cervical mucus important, anyways?

Cervical mucus has a biological purpose. Without its presence, sperm would die very quickly in the vagina. Cervical mucus neutralizes the PH level of the vagina, nourishes and feeds sperm, and allows it to make the journey to the egg. Certain types of cervical mucus also filter out bad sperm, only allowing the “right” sperm to reach the egg. How cool is that?!

Cervical mucus is a hydrogel secreted by your cervical crypts. Your cervix is the entrance to your uterus, and it responds to hormonal changes throughout your cycle (specifically estrogen and progesterone).

Prior to ovulation, an egg is being recruited to mature while estrogen slowly builds, triggering the creation of estrogenic cervical mucus. At ovulation, estrogen is at its peak. Following ovulation is when the hormone progesterone takes over, until your next cycle, when the process starts all over again.

how do i check cervical mucus?

Check for mucus every day, every time you go to the bathroom, as well as pay attention to sensation throughout the day.

Sensation is important for categorizing your cervical mucus for the day. If it helps, close your eyes and decide what the sensation is before you look at the toilet paper. Once you’ve decided sensation, observe the colour, quantity and consistency. Then, at the end of the day, chart the most fertile mucus you observed that day on a paper chart or in an app.

Sensation can also be noted when you’re walking around during the day, you may feel a sensation of something, whether that’s a moist feeling, a dampness, a slickness, or wetness. Note that in your chart as well!

cervical mucus throughout the cycle

What is normal cervical mucus after your period ends, around ovulation, or before your next period? You can read more here.

After menstruation, you may notice several days of dryness, or even some unchanging discharge, before estrogen levels begin to rise.

As estrogen begins to rise and ovulation approaches, you may notice a change in your mucus from dryness or unchanging discharge to something more moist, watery, milky, creamy. This is all normal!

As estrogen rises to peak levels, and you’re around ovulation you may notice ES mucus. Mucus might feel slick or slippery, and you might see a clear or partly clear discharge that looks like raw eggwhites.

Once ovulation has passed, and you’re in the time before your period, you might notice an abrupt dry-up. It’s normal to have some discharge in the luteal phase, especially a sudden feeling of wetness or visible mucus right before your period starts.

Fertility Awareness Educator Note: If you’ve recently come off birth control, you might notice mostly dry or medio days, with very little peak mediodays. Think: a lot of creamy, pasty mucus day after day. This is normal, and your mucus changes will be more subtle, with a gradual improvement over time. If you’ve come off birth control and feel stumped by your mucus, working with an educator might be worth it!

the fertility knowledge collective cervical mucus categories

In Cycle Love we use Fertility Knowledge Collective cervical mucus categories that are simple enough to chart consistently, but nuanced enough to accurately identify fertility patterns across real world cycles.

Instead of over labeling every possible mucus type, we focus on:

sensation at the vulva as you walk around during the day
what is actually seen
the most fertile sign observed that day

At the end of each day, you record:

what you observed throughout the day
with emphasis on the most fertile sign
using one or two words to describe it

Both sensation and appearance matter if the pattern is going to be accurately understood.

how to chart each day

At the end of the day:

Record what was observed throughout the day, prioritizing the most fertile sign
Note sensation at the vulva and appearance of discharge (if any)
Use simple, consistent language

Wiping sensation can be ignored unless it is obviously lubricative.

Cervical Mucus Category: Dry Baseline

Dry Baseline requires all of the following qualities:

Walking Sensation

Nothing felt

Visual

Nothing seen

Wiping Sensation

Ignored

This category reflects progesterone dominance or low estrogen states. It may show up:

after menstruation
after ovulation
or as a consistent baseline pattern

Remember: the vulva is a mucus membrane, like the inside of your mouth. “Dry” does not mean literally desert dry — it means no observable fertility related change.

Medio

Medio includes any of the following qualities without any Peak Medio qualities:

Walking Sensation

Something felt

Visual

Something seen

Wiping Sensation

Ignored

This might include mucus that feels or looks:

creamy
milky
lotiony
opaque
pasty

Medio represents rising estrogen and the approach toward fertility, but without the highly lubricative qualities seen closer to ovulation.

Peak Medio

Peak Medio includes any of the following qualities:

Walking Sensation

Slippery
Intensely Wet

Visual

Clear
Stringy

Wiping Sensation

Lubricative

If any Peak Medio quality is present at any point in the day, the day is charted as Peak Medio.

This category reflects estrogen dominant mucus that supports sperm survival and transport. These are the days closest to ovulation.

Your last day of Peak Medio before a switch to Dry or Medio mucus around ovulation is called peak day. Peak day marks the approximate time of ovulation.

a note on patterns over perfection

Your mucus can absolutely change without ending in ovulation. That doesn’t mean you’re doing anything wrong.

What tends to stand out over time is that true ovulation is usually marked by a very distinct Peak Medio pattern, followed by a clear shift away from fertility.

That’s why we never rely on mucus alone.

In Cycle Love, cervical mucus is always interpreted alongside temperature and, when appropriate, LH testing, so fertility decisions aren’t made on a single sign in isolation.

Mucus is important, mucus is not gross, and mucus is a sign of health. Learning about what your cervical mucus means can help normalize it, turn something that may have been confusing into something empowering.

Cervical mucus is your real time indicator of fertility, and helps you identify ovulation! With that information, you can use the fertility awareness method to avoid pregnancy, and that’s a whole other level of empowering. Happy charting!
