What Are the Types of Cervical Mucus?

Cervical mucus is the discharge created by the cervix, which changes in consistency and appearance depending on where you are in your menstrual cycle. As previously mentioned, these changes can help you recognize different stages of fertility and gauge your overall vaginal health.

While there are variations depending on the individual, the four main types of cervical mucus you may experience during your menstrual cycle include:

• Mucus that is dry or sticky like paste that may be white or light yellow
• White mucus that is creamy and smooth, with the consistency of yogurt
• Mucus that is wet, watery and clear
• Mucus that is slippery and stretchy and looks like raw egg whites

The role of cervical mucus depends on what phase of the menstrual cycle you’re in. When you’re close to ovulation, it helps sperm move through your cervix to fertilize an egg. Other times during the cycle it helps block sperm from entering the uterus when it’s not the ideal time for fertilization. 

Cervical mucus also acts as a protective barrier against infection of the reproductive tract by preventing bacteria and other pathogens from entering. 

What Do the Different Types of Cervical Mucus Mean?

Typically, cervical mucus progresses from the dry or pasty stage through the slippery, egg-white consistency stage as ovulation gets closer, after which it returns to being thick and dry. You are at your most fertile when your cervical mucus is clear, stretchy and slippery and resembles raw egg whites. This type of cervical mucus is sometimes referred to as egg white cervical mucus, or EWCM.

Here’s a more detailed look at the types of cervical mucus and what they mean:

• Dry, sticky or no mucus. This usually happens right after your period and is a low fertility phase.
• Creamy mucus that is smooth, thick, and usually white. It occurs before ovulation and indicates increasing fertility.  
• Cervical mucus that is clear, stretchy and slippery, sometimes called EWCM (egg white cervical mucus), or mucus that is watery and thin. This indicates peak fertility and approaching ovulation.  
• Post-ovulation mucus becomes thicker, stickier and less abundant, then returns to the dry or sticky stage before the beginning of your period, indicating low fertility. 

Arousal fluid may sometimes be confused with cervical mucus. The difference is that arousal fluid is clear, wet, moist, and slippery and usually goes away within one hour.

If you’re trying to get pregnant, one helpful practice is to track your ovulation cycle. You can do this by recording cervical mucus changes based on the information above and having intercourse during your most fertile window.

By the same token, if you want to avoid pregnancy, you can note changes in your cervical discharge and avoid having intercourse during peak fertility. 

Some women may choose to opt out of using hormonal birth control due to potential side effects and track their fertility with cervical mucus monitoring instead.

How Does Cervical Mucus Change During the Menstrual Cycle?

Cervical mucus changes throughout your menstrual cycle due to rising and falling estrogen and progesterone levels. This is what causes shifts in the consistency, color, and amount of your discharge throughout the month. 

According to the Cleveland Clinic, cervical mucus will generally progress through these stages based on a 28-day menstrual cycle: 

Days 1 – 4:  After your period ends, discharge becomes dry or tacky.

Days 4 – 6:  Discharge is sticky, damp and white.

Days 7 – 9:  Discharge is wet and cloudy with a creamy consistency resembling yogurt.

Days 10 – 14:  Discharge is slippery, wet and stretchy, and looks like raw egg whites.

Days 15 – 28:  Discharge is dry or nearly dry until your period starts.

Though every woman’s cervical mucus will change during her cycle, not every woman will experience the same progression. The quantity and consistency of discharge can vary from person to person. 

What Other Factors Can Affect Cervical Mucus Changes?

In addition to hormonal fluctuations, other factors that may influence cervical mucus changes include:

• Stress
• Breastfeeding
• Lubricants used during sex
• Sexually transmitted infections (STIs)
• Surgical procedures that involve the cervix
• Hormonal birth control, which thickens mucus and helps prevent pregnancy
• Vaginal infections such as bacterial vaginosis (BV) or yeast infections
• Certain dietary choices such as processed foods, foods high in sugar and foods high in trans fats
• Medications such as antihistamines, antidepressants, hormone therapies and some antibiotics

If you’re interested in tracking your cervical mucus for fertility awareness or to identify potential health issues, you can do this by:

• Using your fingers. Place a clean finger in your vagina, then remove it and look at the mucus.
• Checking your underwear. Note any discharge you see when you go to the bathroom.
• Using toilet paper. Check your toilet paper for cervical mucus after peeing and wiping.

If you’re monitoring your cervical mucus to gauge fertility levels, you may want to keep a journal and record mucus characteristics and changes daily, starting after your period ends.

What Are Signs of Abnormal Cervical Mucus?

Signs of abnormal cervical mucus may include:

• Mucus that is funky or foul-smelling
• Discharge that has a cheese-like texture
• Vaginal discharge that doesn’t stop
• Yellow, green or gray discharge, especially if itching or a foul odor is also present 
• Discharge not related to implantation or menstruation that is slightly pink or brown in color 
• Any other differences in your discharge that are not included in the sections above about what normal changes to expect during the menstrual cycle 

Abnormal cervical mucus may indicate infection, ovulation problems, hormonal imbalances or other health conditions.

If you notice a change in discharge that is not normal for you, especially if you have other symptoms like itching, burning or pain, we invite you to contact us for an appointment so we can provide the proper diagnosis and treatment.
