Key Takeaways

Vaginal discharge is normal and essential — it is your body's self-cleaning mechanism
Clear to white discharge is typically healthy; yellow-green, grey, or chunky white may indicate infection
Discharge changes throughout your menstrual cycle — this is expected, not alarming
Odour alone is not always a sign of infection — a mild scent is normal
See a doctor if discharge is accompanied by itching, burning, strong odour, or unusual colour

Your vaginal discharge is trying to tell you something, and the chances are nobody ever taught you how to listen. In a culture where discussing periods still meets resistance at the dinner table, the nuances of vaginal discharge — what colour is normal, what consistency should worry you, what changes through the month — are treated as mysteries best left unsolved.

This is a problem. Discharge is one of the most reliable indicators of vaginal and reproductive health. Learning to read it is as fundamental as learning to check your temperature when you feel unwell. It is not complicated, it is not embarrassing, and by the end of this guide, you will understand exactly what your body is communicating.

What Discharge Actually Is

Vaginal discharge is a combination of fluid produced by the cervix and vaginal walls, along with dead cells and healthy bacteria (primarily Lactobacillus). It serves several critical functions:

Self-cleaning: The vagina cleans itself from the inside out. Discharge carries away dead cells and potential pathogens.
pH maintenance: Healthy discharge maintains vaginal pH between 3.8 and 4.5 — acidic enough to inhibit bacterial and fungal overgrowth.
Lubrication: Discharge keeps vaginal tissues moist and comfortable.
Fertility signalling: Discharge changes in consistency around ovulation to facilitate or hinder sperm transport.

The average person with a vagina produces 1-4 ml of discharge daily. This is not a malfunction — it is evidence that the system is working.

The Colour Guide

Clear

What it means: Completely normal. Clear discharge is healthy vaginal fluid and often increases around ovulation, during arousal, or with exercise. If it is stretchy and resembles raw egg white, you are likely ovulating — this consistency helps sperm travel efficiently.

When to worry: Clear discharge that is excessive in volume (soaking through underwear multiple times a day) combined with other symptoms may warrant a check-up, but clear discharge alone is almost always fine.

White

What it means: Normal, especially at the beginning and end of your menstrual cycle. Thin, milky white discharge is healthy. The whiteness comes from a higher concentration of cells and bacteria in the fluid.

When to worry: If the white discharge is thick, clumpy, and resembles cottage cheese, it may indicate a yeast infection (candidiasis). Yeast infections are also typically accompanied by itching, burning, and sometimes redness or swelling. The discharge itself is distinctive — if it looks like paneer, your body is telling you something.

Pale Yellow

What it means: Light yellow discharge can be normal, particularly if it has no strong odour and no accompanying symptoms. It may simply be discharge that has been in contact with air and oxidised slightly on your underwear.

When to worry: Deep yellow with a strong, unpleasant odour may indicate bacterial infection or an STI. If it is accompanied by pain, itching, or burning, see a gynaecologist.

Green or Yellow-Green

What it means: This is almost always a sign of infection. Green discharge is commonly associated with trichomoniasis (a sexually transmitted parasitic infection), bacterial vaginosis, or other infections. It is often frothy, has a strong smell, and may be accompanied by irritation.

When to worry: Immediately. Green discharge warrants a medical visit. Do not attempt to self-treat with over-the-counter products or home remedies. A proper diagnosis requires testing, and the appropriate treatment depends on the specific cause.

Grey

What it means: Grey discharge is the hallmark of bacterial vaginosis (BV), which occurs when the balance of vaginal bacteria shifts and harmful bacteria overgrow. BV is characterised by thin, greyish discharge with a strong, fishy odour that may intensify after intercourse.

When to worry: BV is not an STI but it does require medical treatment (typically antibiotics). Left untreated, it can increase susceptibility to STIs and cause complications during pregnancy.

Pink

What it means: Pink discharge usually contains a small amount of blood. It can occur around ovulation (mid-cycle spotting), at the very beginning or end of your period, after intercourse (due to minor cervical irritation), or during early pregnancy (implantation bleeding). It is frequently harmless.

When to worry: Persistent pink discharge outside of your period, especially post-menopause, should be evaluated by a doctor. During pregnancy, any bleeding warrants a call to your healthcare provider.

Brown or Dark Red

What it means: Old blood. Brown discharge is typically blood that has taken longer to exit the body, so it has oxidised and changed colour. It commonly appears at the very end of your period, between periods (spotting), or during early pregnancy.

When to worry: Occasional brown discharge is normal. Persistent brown discharge between periods, particularly if it is new for you, should be checked by a gynaecologist to rule out cervical or uterine issues.

Expert Insight Gynaecologists recommend tracking your discharge patterns for a few months to establish your personal baseline. What is "normal" varies between individuals. Once you know your own cycle's pattern, you will be much better equipped to recognise when something genuinely changes. Many period-tracking apps now include discharge tracking features for this purpose.

Changes Through Your Menstrual Cycle

Discharge is not static — it changes predictably throughout the month:

Days 1-5 (Period): Menstrual blood. Discharge is not typically noticeable.
Days 6-9 (Post-period): Minimal discharge. May feel dry.
Days 10-14 (Approaching ovulation): Increasing discharge, becoming clear, slippery, and stretchy — resembling raw egg white. This is peak fertility.
Days 15-22 (Post-ovulation): Discharge becomes thicker, cloudier, and decreases in volume.
Days 23-28 (Pre-period): Discharge may thicken further or become slightly sticky. Some people notice a small amount of brown spotting.

When to See a Doctor

Book an appointment with a gynaecologist if you experience any of the following:

Green, grey, or deep yellow discharge
Cottage cheese-like texture with itching
Strong, foul, or fishy odour
Discharge accompanied by pelvic pain or fever
Bleeding between periods or after menopause
Any sudden change from your normal pattern that persists for more than a few days

What Not to Do

Do not douche. Ever. Douching disrupts the vaginal microbiome and increases infection risk. The vagina is self-cleaning — douching is like pressure-washing a self-cleaning oven.
Do not use scented products near the vagina. Perfumed soaps, sprays, and wipes alter pH and can cause irritation or infection.
Do not wear wet underwear. Moisture creates an environment for bacterial and fungal growth. Change underwear if it becomes wet or damp.
Do not self-diagnose using Google images. Discharge colour can look different depending on underwear colour, lighting, and timing. If you are concerned, see a doctor rather than comparing photos online.

Understanding your discharge is an act of body literacy. It is not gross, it is not embarrassing, and it is not optional. Your body is communicating its health status every single day — learning to listen is one of the most empowering things you can do for yourself.

Common Questions About Vaginal Discharge Colour Guide

Is it normal to have discharge every day?

Yes. Daily discharge is completely normal and is a sign that your vaginal ecosystem is functioning properly. The amount varies between individuals and fluctuates throughout the menstrual cycle, but some discharge every day is expected and healthy.

Does discharge mean I have an infection?

No. Discharge is a normal bodily function. Only discharge with unusual colour (green, grey), unusual consistency (cottage cheese), strong odour, or accompanying symptoms (itching, burning, pain) may indicate an infection. Clear, white, or pale yellow discharge without symptoms is typically healthy.

Can diet affect vaginal discharge?

Indirectly, yes. A diet high in sugar can promote yeast overgrowth, potentially leading to yeast infections and changes in discharge. Adequate water intake supports healthy mucus membrane function. Probiotic-rich foods (yoghurt, fermented foods) may support a healthy vaginal microbiome. However, extreme dietary claims about discharge are largely unsubstantiated.

Does discharge increase with arousal?

Yes. Sexual arousal triggers a process called transudation, where blood flow to the vaginal walls increases and fluid seeps through the tissue, creating natural lubrication. This is a different process from cervical discharge and is a healthy, normal response to arousal. Some people produce more arousal fluid than others — both are completely normal.

Should I wear pantyliners for discharge?

This is a personal choice. Some people find pantyliners helpful for comfort, especially during the discharge-heavy phases of their cycle. If you use them, choose unscented, breathable liners and change them regularly. Cotton underwear alone is also perfectly adequate for managing normal daily discharge.
