What Does Normal Discharge Look Like?

There are many different types of vaginal discharge, ranging from healthy to abnormal. But what does normal discharge look like? And what are some signs that your vaginal discharge is a sign of infection? Keep reading to learn more.

What is vaginal discharge? 

Vaginal discharge is the fluid made by your cervix and vagina. Discharge is a mix of cervical mucus, bacteria, dead vaginal skin cells from the lining of the vagina (epithelium), and vaginal fluid. Practically any fluid leaving the vagina (including cervical mucus and sexual arousal fluid) can be characterized as vaginal discharge.

Although many of us grew up believing discharge is gross or a sign that your vagina is "dirty", it's actually a signal of good reproductive health. Vaginal discharge helps to clear out old cells and unwanted bacteria, and not only does it keep your vagina clean and lubricated, but it can also be an important indicator of your overall vaginal health and ability to prevent vaginal infections.

What does normal discharge look like? 

When it comes to the human body, the word “normal” is hard to define. What’s normal for you might be atypical for your sister or friend. But many factors can influence the quantity, consistency, and color of your vaginal discharge, and there are a few things you can keep in mind as you figure out your “normal.”

Healthy discharge will consist primarily of the mucus produced by the cells of the cervix (also known as cervical mucus, or CM for short). Vaginal discharge changes throughout your menstrual cycle in response to hormonal changes.

It’s common for vaginal fluid to increase in volume the closer you are to ovulation, which makes monitoring the consistency and quantity of your discharge on an ongoing basis a good way to keep track of general fertility. Note that if you take hormonal birth control, you might not be able to see these changes. 

Typically speaking, healthy vaginal discharge will follow a monthly pattern. Normal vaginal discharge types include:  

• Dry  discharge: after your period, there may be little to no cervical mucus or discharge present.
• Sticky and white: as estrogen levels start to rise, CM becomes sticky and pasty (often crumbly and white when dried). 
• Creamy vaginal discharge: as the water content increases throughout your menstrual cycle, discharge can start to look milky white, similar to lotion.‍
• Clear sticky vaginal discharge :  just before ovulation, CM becomes clear and resembles the consistency of raw egg whites. After ovulation, CM returns to dry and sticky until your next period and the cycle continues.

What amount of vaginal discharge is normal?

As we explained above, "normal" is a tricky term when it comes to discharge. The amounts of discharge may vary from person to person but, on average, a premenopausal woman has one-half to one teaspoon (2 to 5 mL) of discharge daily. 

It's pretty normal to notice that the amount of vaginal discharge you make changes throughout the month, too. This is because the glands in the cervix produce and release cervical mucus, which can change in volume and texture in response to hormonal fluctuations during your menstrual cycle. 

You may notice more discharge in the days leading up to ovulation (about halfway through your cycle), early pregnancy, and when you start taking a new form of hormonal birth control. Some infections can also increase the quantity of vaginal discharge, but in most cases, you'll experience vaginal symptoms like itching or burning, or a foul odor, too. 

Why does my vaginal discharge smell?

Normal vaginal discharge has a slightly tangy or musky smell that is entirely unique to you. Remember, it’s a bodily function, so it’s ok for it to have a mild odor. That said, any sudden or significant changes in odor (especially if it’s fishy or “rotten”) could indicate an imbalanced microbiome  —  and may indicate an untreated infection.

Abnormal vaginal discharge

In addition to smell, it’s important to look out for any big changes in the color of your vaginal discharge.

Gray discharge

Gray-ish discharge accompanied by a fishy odor, and with or without the presence of vaginal pain, itching, and burning, can be a sign that something down there is “off.” Most commonly, these symptoms are caused by a vaginal infection called bacterial vaginosis (BV). Bacterial vaginosis happens when an overgrowth of "bad" bacteria throws off your microbiome's normal balance.

Bacterial vaginosis  is an incredibly common vaginal infection and the number one culprit of abnormal vaginal discharge.

White and thick discharge

Vaginal itching and white discharge that looks like cottage cheese may indicate a yeast infection, especially if it's accompanied by swelling and redness (particularly around the vaginal opening). One of the main symptomatic differences between a yeast infection and bacterial vaginosis is the kind of smell: BV is often fishy, while a yeast infection is usually odorless or has a slightly sour smell (like beer or bread).

Caused by an overgrowth of the Candida fungus, yeast infections affect up to 50% of healthy women at one point or another during their lifetime, so rest assured that you’re not alone. 

Thick, white discharge can also indicate a condition called cytolytic vaginosis (CV), also known as Lactobacillus overgrowth syndrome (or Doderlein’s cytolysis). CV is a condition that arises when the healthy bacteria (lactobacilli) over-multiply in your vaginal microbiome and cause vaginal discomfort.

Frothy yellow or green discharge, genital itching or burning, soreness, and a foul smell are all symptoms of a treatable sexually transmitted infection (STI) called trichomoniasis. However, many individuals with trichomoniasis are completely asymptomatic. 

Aerobic vaginitis (AV) is a condition that causes vaginal discomfort and inflammation. It was only identified in research as distinctly separate from bacterial vaginosis in 2002. However, a key distinction is the symptom of sticky, yellow vaginal discharge that is associated with aerobic vaginitis, but not BV.

Pink or brown  discharge

Brown discharge is usually nothing more than the result of old blood becoming oxidized, most commonly at the beginning or end of the menstrual cycle. This is completely normal and also can differ between cycles. 

That said, experiencing any brown or pink discharge that is abnormal for you and your body can be indicative of an irregular cycle, or a sign of something more serious — in any case, talking to a doctor can help. 

How to prevent abnormal vaginal discharge 

Your discharge is often related to how well-balanced your vaginal microbiome is, so one way to normalize your discharge is to take better care of your microbiome (and overall reproductive health). A general guide to best practices includes:

• practicing safe sex (using a condom or dental dam)
• cover sex toys with a condom during partnered sex, and make sure to clean them after each use
• get regular STI tests
• avoiding the use of douches and scented feminine hygiene products
• cutting back on sugar and alcoholic drinks
• changing quickly out of wet or sweaty clothes.

We know you’ve probably heard these strategies before, and that they don’t always help — it can be frustrating to get the same advice without different results.

FAQs

How do I know if my discharge is normal?

Track your discharge! The best way to know if your discharge is normal is to get familiar with what’s normal for you. The texture, color, and quantity of discharge can change from day to day, so the key is getting acquainted with what fluctuations are expected for your body. Generally speaking, though, normal vaginal discharge is clear or white, with a sticky or stretchy consistency and a mild odor. Any drastic change in the color, smell, consistency, and quantity of your vaginal discharge could be a sign of an infection.

What is unhealthy discharge like?

Some types of abnormal discharge to look out for are green, gray, or yellow discharge that is thin or foamy, thick and chunky white discharge (like cottage cheese), and any type of discharge that has a foul or fishy odor. 

What does STD discharge look like?

One of the most common signs of a sexually transmitted disease (STD) is a big change in the color, consistency, or smell of your vaginal discharge. Even if you're not showing any symptoms, abnormal vaginal discharge could be a sign of a sexually transmitted infection (STI). For instance, chlamydia can cause white or yellow discharge with a strong, unpleasant smell. Trichomoniasis can cause gray or green, frothy discharge that smells fishy or "rotten," while gonorrhea can lead to yellow or greenish discharge with a watery consistency.

What shades of discharge are normal?

Healthy discharge can range from clear to white and even pale yellow. Right before or after your period, you might even notice that your discharge has a brown or pink hue to it thanks to the presence of blood.
