Fertile cervical mucus is a clue that ovulation is coming. If you want to get pregnant, you need to have sex before ovulation.

You can predict this by checking and tracking cervical mucus changes. 

Yes, this will mean looking and (usually) touching your vaginal discharge. You may feel squeamish about it, but... this is your body! 

Knowing how your body works can be really empowering. It's been years since I was actively trying to conceive.

And yet, even now, I am always aware of where I am in my cycle and when I'm about to ovulate. 

It truly becomes second nature!

What Is Cervical Mucus?

Cervical mucus is secreted by glands found in and around the cervix. Hormonal changes throughout a woman's reproductive cycle change the amount and consistency of this mucus. Cervical mucus may also be called cervical fluids. 

The job of cervical mucus is to either...

  • prevent things from entering the uterus through the cervix, or
  • to nourish and help transport sperm through the cervix into the uterus 

Just before ovulation occurs, the hormone estrogen causes an increase in cervical mucus and changes it into a stretchy, viscous like substance. This helps sperm survive and swim.

After ovulation, the hormone progesterone causes cervical mucus to become sticky and thick. This stops sperm (and any other foreign substance) from getting through to the uterus.

Understanding the Connection Between Ovulation and Cervical Mucus

If you already track your body basal temperature (BBT), adding cervical mucus tracking is a good idea.

Your BBT will tell you if and when you ovulated after it happened. Cervical mucus changes can tell you before you ovulate. 

As ovulation approaches, your cervical mucus changes from a consistency that's not sperm friendly to a more fertile variety.

While everyone's body is different, the general changes that cervical mucus go through are...

  • dry or sticky
  • too creamy, like lotion
  • to wet and watery
  • to a raw egg white consistency
  • then, back to dry and sticky

When your cervical mucus is in the wet or raw-egg-white consistency stage, ovulation is approaching. This is the best time to have sex if you want to get pregnant.

How to Check Your Cervical Mucus:

  1. First, wash and dry your hands well.

  2. Find a comfortable position, either by sitting on the toilet, squatting, or standing up and putting one leg up on the bathtub edge or toilet seat.

  3. Reach one finger inside your vagina; your index or middle finger is probably best. (Be careful not to scratch yourself.)

    Depending on how much cervical mucus you're producing, you may not need to reach so far, but getting a sample from near your cervix is ideal.

  4. Remove your finger from your vagina and observe the consistency of whatever mucus you find.

    Do this by both looking at the mucus and rolling what you find between two fingers (usually your thumb and index finger). Try pressing your fingers together and then slowly moving them apart.

    • If what you find seems sticky, or findings are scant, you're probably not ovulating yet.
    • If what you find is creamy, ovulation may be coming, but not just yet.
    • If what you find is wet, watery, and slightly stretchy, ovulation is very likely close. Find time for some baby-making sex.
    • If what you find is very wet, stretches between your fingers for an inch or more, and resembles a raw egg white, your cervical mucus is very fertile. Ovulation is right around the corner, and now is the ideal time for intercourse.
  1. If you are charting your BBT, you should mark down on your chart your cervical mucus findings.

    Abbreviations often used are S for sticky, C for creamy, W for wet, and EW (or EWCM) for egg-white cervical mucus.

Tips for Checking Cervical Mucus

Don't check your cervical mucus during or right after sex. 

Also, avoid checking when you're feeling sexually aroused.

Arousal fluids are not the same as fertile cervical mucus, but you probably won't be able to tell the difference. So don't check at these times.

Checking after sex is also a bad idea. It's too easy to confuse semen for cervical secretions.

You can check your cervical mucus by looking at the toilet paper or your underwear. 

Not everyone is comfortable with putting their finger inside to check themselves. But you don't have to.

You can instead pay attention to how wet your vulva feels on a day to day basis, pay attention to the discharge on your underwear, or look at the toilet paper after urination.

There is, in fact, an entire method based on this: the Billings Ovulation Method.  

With all that said, it's easier for many women to physically check themselves and reach inside. 

Consider checking your cervical mucus after bowel movements. 

Of course, first, wash your hands well! But if you have trouble finding cervical mucus, it may be easier after a bowel movement.

Having a bowel movement moves down any vaginal discharge closer to the entrance of your vagina.

If you have multiple patches of fertile cervical mucus, look for additional ovulation signs beside CM.

Some women, especially those with PCOS, have several patches of fertile-looking cervical mucus throughout their cycle.

If this is your situation, predicting ovulation by tracking cervical mucus might not work well for you.

You should consider paying attention to other ovulation signs, like cervical position changes.

You may also want to chart your basal body temperature, so you know which (if any) of the fertile cervical fluids indicated ovulation. 

Some medication may interfere with your cervical fluids.

Antihistamines dry up more than your sinuses -- they also dry up your cervical fluids.  

Ironically, Clomid can prevent you from having fertile quality cervical mucus. In this case, you might not find as much fertile cervical mucus before ovulation.

In this case, you might want to try using an ovulation predictor kit to detect ovulation instead.

If you never get fertile quality cervical mucus, tell your doctor. 

Lacking fertile quality cervical mucus can be a sign of a hormonal imbalance or fertility problem. 

Cervical mucus that doesn't ever become fertile is sometimes referred to as hostile cervical mucus.

You may see fertile cervical mucus again right before your period.

Some women notice that their cervical mucus becomes wet or almost egg-white like again right before menstruation.

Obviously, this isn't a sign of impending ovulation.

Women sometimes wonder if getting a lot of cervical mucus just before their period is due is a possible early pregnancy sign. 

The fact of the matter is, it's almost impossible to tell the difference between "early pregnancy" cervical mucus and regular "just before your period comes" cervical mucus.

You may confuse semen with cervical mucus.

A day or two after sexual intercourse, you may confuse semen with wet cervical mucus.

With experience, you can learn how to differentiate the two.

But for the purposes of getting pregnant, assume that you may be approaching ovulation and mark your calendar or chart accordingly.

Do not attempt to wash away your natural vaginal fluids!

Cervical mucus is normal and healthy. Some women wash away "ovulation secretions" thinking they are unhygienic or unhealthy.

Don't do this! Douching can actually decrease your fertility.
