Vaginal discharge, often a source of worry or confusion, is actually a natural and healthy part of female intimate health.
These vaginal secretions, which vary in color and consistency and are found in your underwear, are made up of dead cells and cervical mucus. This type of vaginal discharge cleans and protects the vagina by maintaining an acidic pH.
Yet, their appearance can vary—heavier before ovulation, creamier at the start of pregnancy, or changed by contraception—which can cause confusion.
This new article will help you recognize normal signs, identify warning signals (strong odor, itching, unusual color), and adopt the right habits to maintain this delicate balance, while avoiding mistakes like self-medicating.

What is vaginal discharge?
White discharge: normal vaginal discharge
Did you know that vaginal discharge is a sign of good health? White discharge, also known as physiological leukorrhea, is a normal and beneficial vaginal secretion. It appears at puberty and disappears at menopause, indicating that the female reproductive system is functioning properly.
Where does vaginal discharge come from?
White discharge comes from the glands of the cervix and the vagina.
What is the purpose of vaginal discharge?
Made up of cervical mucus, dead vaginal lining cells, and fluids, they play a protective role. They cleanse the vagina, remove dead cells, maintain an acidic pH to keep out germs, and lubricate the vaginal walls.
These secretions therefore play a very important role in your intimate health.
Normal vaginal discharge: what does it look like?
Their appearance changes depending on the phases of your menstrual cycle, under the influence of hormones. They can be:
translucent,
whitish
or slightly yellowish.
They can vary in consistency:
with a creamy texture,
stringy
or sticky.
Odor level:
they can be odorless
or have a slight odor.
Normal, everyday discharge does not cause any discomfort or pain.
Important to know: their quantity increases at the beginning of pregnancy or when using hormonal contraception.
Another important point: vaginal discharge can discolor underwear, a phenomenon caused by vaginal acidity. This is a sign of a healthy balance.
Normal vaginal discharge: how to recognize it
The appearance and composition of normal vaginal discharge
Normal vaginal discharge, or leucorrhea, is a sign of a healthy intimate balance. It appears whitish, clear, or slightly yellowish, without a strong odor. The texture changes with your cycle: it can be watery, creamy, pasty, or stretchy like egg whites.
Underwear discoloration is normal and caused by the acidity of vaginal pH (between 3.8 and 4.5), which is maintained by lactobacilli, beneficial bacteria that produce lactic acid.
“Normal vaginal discharge is a sign of good health, just like regular periods.”
Their role is essential: to protect against infections by preventing the growth of harmful germs like fungi or bacteria. They naturally clean the vagina and lubricate its walls. There are three main components:
Cervical mucus: secreted by the cervix, it changes under the influence of estrogen, ranging from creamy to viscous and transparent (like egg whites around ovulation).
Cyprine: Transparent, fluid liquid released during sexual arousal to facilitate intercourse.
Dead cells: Shed from the vaginal walls, they form a sticky mixture that helps with cellular renewal.
How vaginal discharge changes throughout the menstrual cycle
Discharge adapts to your hormones.
After your period (during the follicular phase), with low estrogen, they are dry or creamy.
As ovulation approaches, rising estrogen levels make it more abundant, clear, and stretchy—sometimes stretching several centimeters. This “fertile” mucus, explained in the menstrual cycle guide, helps sperm move more easily. It signals the peak fertility period.
After ovulation, progesterone takes over: discharge becomes thicker, opaque, and sticky. These changes signal the end of the fertile window. These variations are normal and show a healthy hormonal balance.
Vaginal discharge and life stages: adolescence, pregnancy, and birth control
Beyond the menstrual cycle, it’s normal to notice white discharge at certain times in a woman’s life, and it’s usually nothing to worry about.
Adolescence boosts estrogen production, leading to more frequent discharge. Explaining this to a teen helps reassure them it’s normal and avoids the use of scented soaps, which can disrupt vaginal flora.
During pregnancy, discharge increases to strengthen the barrier against infections, but remains odorless and non-irritating.
Hormonal contraceptives affect discharge: the combined pill or vaginal ring stabilize it, while progestin-only methods (implant, IUD) can cause irregular bleeding.
During menopause, this decrease is normal, but unusual discharge (strange color, strong odor) requires a consultation to rule out an infection.
Abnormal vaginal discharge: warning signs to watch for
Warning signs not to ignore
Vaginal discharge can naturally vary in consistency and amount, but certain abrupt changes should be taken seriously. A sudden shift in color, smell, or texture is often the body’s first warning sign. These changes can occur outside your menstrual cycle or after unprotected sex and deserve immediate attention.
Unusual color: Greenish, yellowish, or grayish tones can indicate an imbalance. Green often suggests a bacterial or parasitic infection, yellow may indicate bacterial vaginosis, while gray is common with advanced yeast infections.
Abnormal texture: Clumpy, foamy, or stringy with no relation to your menstrual cycle. A thick, curdled milk-like consistency indicates a yeast infection, while a foamy texture is typical of sexually transmitted infections.
Strong odor: A foul, fishy smell often indicates an infection. This odor tends to get stronger after sex or during your period, especially if you have bacterial vaginosis.
Itching or burning: These symptoms together indicate irritation or infection. Intense itching that gets worse at night is characteristic of a yeast infection, while burning during urination is common with trichomoniasis.
Pelvic pain: Discomfort in the lower abdomen or during sex should not be ignored. This pain can radiate to the lower back and may come with difficulty urinating.
If you have one or more of these symptoms, seek medical advice quickly. Don’t ignore these warning signs: early treatment helps prevent complications. There are many possible causes for these abnormal discharges, ranging from a yeast infection treatable in a few days to sexually transmitted infections that require close monitoring.
Decoding color and texture: what do they mean?
To tell the difference between normal and abnormal discharge, here’s a guide that can help you. This table summarizes the potential causes, but only a healthcare professional can give a diagnosis.
| Types of discharge | Color and Texture | Odor | Associated symptoms | Possible cause |
| Vaginal yeast infection (Candidiasis) |
White, thick, and clumpy (cottage cheese texture) |
None or light |
Severe itching, burning, redness |
Yeast infection (Candida albicans) |
| Bacterial vaginosis |
Grayish, yellowish, or greenish fluids |
Strong, fishy odor |
Little to no itching |
Vaginal flora imbalance |
| Trichomoniasis (STI) |
Yellowish or greenish, foamy, abundant |
Uncomfortable |
Itching, burning during urination |
Sexually Transmitted Infection |
| Pink or brown discharge |
Pink or brown, often light |
Usually absent |
May occur outside of your period |
Presence of blood, known as spotting |
Pink or brown discharge deserves special attention. If it occurs outside your period, it can have a variety of causes: hormonal imbalance, infection, or a side effect of birth control. Careful monitoring is needed to watch for warning signs. If it happens repeatedly or is accompanied by heavy bleeding, see a doctor.
⚠️ This chart is not a substitute for medical advice. If you’re unsure, it’s better to consult a doctor quickly. Untreated infections like bacterial vaginosis or trichomoniasis can lead to serious complications. For example, trichomoniasis can cause salpingitis (infection of the fallopian tubes) in women or prostatitis in male partners. For daily intimate hygiene, avoid harsh products that disrupt vaginal balance. Choose a gentle soap or a fragrance-free cleansing gel without parabens or foaming agents.
How to manage vaginal discharge on a daily basis?
Moisture, discoloration of underwear: is this normal?
White vaginal discharge is a natural defense mechanism. Made up of dead cells, cervical mucus, and lactobacilli, it maintains an acidic pH (between 3.8 and 4.5) thanks to lactic acid production. This pH prevents the growth of harmful bacteria and fungi like Candida albicans.
Discoloration of underwear comes from the lactic acid in vaginal discharge. This compound interacts with fabric dyes, causing localized fading. It’s a sign of a healthy vaginal microbiome. If you’re unsure if your discharge is normal, check its smell: a slightly sour scent is normal, but a rotten fish odor signals an infection.
Intimate hygiene and protection: best practices to adopt
The vagina does not require any internal cleaning. Vaginal douching, used by 20% of women in the United States, destroys lactobacilli and doubles the risk of bacterial vaginosis. It also increases the risk of pelvic inflammatory disease by 73% and ectopic pregnancy by 76%.
Choose organic cotton underwear that’s breathable and free of irritating seams (which is the case for all our Louloucup period panties). Avoid synthetic fabrics like nylon, which trap moisture. If you tend to sweat a lot, go for styles with a cotton insert and Tencel elastic waistband for better airflow. Sleep without underwear to let your vulva breathe.
When should you see a doctor and how can you maintain intimate balance?
The importance of not self-diagnosing
Can an intimate infection be treated without medical advice? Caution: the symptoms of a yeast infection (itching, thick discharge) and those of bacterial vaginosis (unpleasant odor, grayish discharge) can be similar. The wrong treatment could make things worse.
An over-the-counter antifungal from the pharmacy can fail if the cause is bacterial. Broad-spectrum antibiotics, which often trigger imbalances, can also destroy beneficial bacteria. Without an accurate diagnosis, irritation persists and the risk of recurring infection increases.
A medical consultation allows for identifying the responsible germ through a sample. A doctor can prescribe a targeted antibiotic for bacterial vaginosis or an appropriate antifungal for yeast infections, preventing complications like lesions or chronic infection.
Good habits for a healthy vaginal flora
Why do some women develop imbalances more often? The answer lies in daily habits. Here are the key practices for preserving this natural protective barrier:
Gentle hygiene: daily external washing with a soap-free and fragrance-free product is enough. Lukewarm water is ideal.
Avoid vaginal douching: these practices disrupt the acidic pH (3.8 to 4.5) needed for the balance of lactobacilli.
Clothing choice: choose cotton for your underwear. Synthetic fabrics encourage moisture.
Proper hygiene products: changing them regularly (every 4 to 6 hours) helps limit bacteria.
Protection during sex: Condoms protect against STIs, which are often the cause of abnormal discharge.
An imbalance can lead to urinary tract infections or an overgrowth of Candida albicans. If in doubt, consult a healthcare professional. Prevention remains the best way to maintain a vaginal microbiome made up of 90% lactobacilli, the true guardians of your intimate balance.
What to remember about vaginal discharge
Vaginal discharge is a natural phenomenon that plays a vital role in maintaining intimate health. It cleanses the vagina, renews cells, and protects against infections thanks to its acidic pH. Its appearance changes depending on your menstrual cycle, pregnancy, or arousal, but this is nothing to worry about.
Most women notice changes related to hormones. However, a strong odor, unusual colors (green, gray), or itching require a prompt medical consultation.
Avoid vaginal douching and scented products that disrupt this balance. Cotton underwear and gentle hygiene are enough. Knowing your body helps you spot warning signs and avoid complications like yeast infections.
In short, pay attention to and respect your body: it gives you signals, and it’s up to you to listen and interpret them. Staying attentive is the best prevention.
Vaginal discharge is a natural phenomenon and a sign of healthy intimate health. Their appearance varies according to your cycle and life stages. If you notice any suspicious changes (color, odor, itching), consult a healthcare professional. Learning to observe and understand these signals helps you better maintain your vaginal balance every day.
FAQ: Vaginal discharge
What causes white vaginal discharge?
Vaginal discharge, also known as leukorrhea, is completely normal and natural. It's produced by glands located at the cervix and in the vagina. Its appearance is linked to hormonal activity and the menstrual cycle. It consists of cervical mucus, sexual lubrication fluid, and dead cells from the renewal of the vaginal lining. The amount and consistency vary depending on the phase of the cycle, age, and hormonal changes such as pregnancy or using hormonal contraception.
What does milky white discharge mean?
A milky or creamy white discharge is usually completely normal. It’s part of the normal physiological changes in vaginal secretions. This type of discharge often appears at the beginning or end of your cycle, and can also occur during pregnancy. There’s no reason to worry unless it’s accompanied by itching, irritation, or an unpleasant odor. The milky texture simply reflects the natural evolution of cervical mucus throughout the cycle.
When should you worry about vaginal discharge?
You should see a doctor if your discharge suddenly changes color, texture, or smell, or if it comes with concerning symptoms. A strong, unpleasant odor (like fish), an unusual color (greenish, yellowish, grayish), an abnormal texture (clumpy, foamy), as well as itching, burning, redness, swelling of the labia, or lower abdominal pain are all warning signs.
Why do I have daily vaginal discharge?
Daily vaginal discharge is completely normal and is part of the natural functioning of the female body. It’s a sign that your vagina is self-cleaning and is an indicator of good intimate health. The amount and texture can vary depending on the phase of your cycle, your age, and hormonal changes. It’s common to have discharge every day, and feeling dampness in your underwear is perfectly natural, especially around ovulation or during pregnancy when it tends to increase.
What do odorless white vaginal discharges mean?
Odorless or slightly acidic-smelling discharge is perfectly normal. It indicates a healthy acidic vaginal pH, which is essential for protecting against infections. This discharge can be creamy, pasty, or stretchy, and varies depending on the phase of your cycle. No smell or a faint one is reassuring, while a foul-smelling discharge could signal an infection (trichomoniasis, bacterial vaginosis).
What does thick, white discharge mean?
A thick, white, paste-like discharge is one of the normal forms that cervical mucus can take. It’s common at the beginning or end of your cycle, or after ovulation. This kind of discharge is part of the natural variations in vaginal secretions. There’s no need to worry unless it comes with other unusual symptoms like itching, a strong odor, or pain.
What does it mean if your vaginal discharge is very watery?
Thin or watery vaginal discharge is completely normal, especially around ovulation when cervical mucus becomes very abundant and clear, resembling egg whites. This very fluid texture helps sperm move during the fertile period. It can also appear in early pregnancy. This type of discharge is reassuring as long as it’s odorless and not accompanied by other symptoms.
What kind of vaginal discharge can indicate pregnancy?
Heavier, creamier, or egg white-like vaginal discharge can be an early sign of pregnancy, appearing as soon as six days after ovulation. This is due to the first hormonal changes from embryo implantation. However, this symptom isn’t specific and can also happen before a normal period. To confirm pregnancy, a pregnancy test is still necessary, since vaginal discharge can have many other causes.
