Is Increased Vaginal Discharge Normal? Colour, Texture, Odour and When to Seek Care
Many women notice discharge on their underwear and wonder whether they are not clean enough. In fact, the vagina naturally produces fluid that helps keep it moist and healthy. The amount and texture of discharge can also change throughout the menstrual cycle and at different stages of life. The aim is not to have “no discharge at all”, but to understand your usual pattern and recognise meaningful changes.
At a glance: normal, notice and seek care
| Usually normal | Notice and observe | Seek medical care |
|---|---|---|
| Clear to white; no strong or unpleasant odour; no itching, burning or pain; changes are consistent with your usual pattern or cycle. | A short-term increase in discharge without other symptoms may be related to ovulation, the menstrual cycle, pregnancy, sexual arousal or contraception. Seek advice if it persists or is clearly different from your usual pattern. | Grey, yellow, green or blood-stained discharge; a strong fishy or foul odour; itching, redness, burning, painful urination, pelvic pain, sores or blisters; persistent or recurrent symptoms. |
What does normal vaginal discharge usually look like?
Normal discharge is usually clear to white and does not have a noticeable or strong odour. It may be thicker and sticky, or wetter and more slippery. Its amount and composition can change during the menstrual cycle.[2][3] Everyone’s “normal” is slightly different, so it is more useful to compare the discharge with your usual pattern and check whether any discomfort is present.
Discharge comes from the vagina. The vulva is the external skin and tissue. The vagina is self-cleaning, so everyday care should focus on gently cleaning the vulva. Water, cleansers and other products should not be flushed or inserted into the vagina.[1][2][3]
Why does vaginal discharge sometimes increase?
The amount of discharge naturally rises and falls. The following situations may make it more noticeable. However, if there is also an unusual odour, itching, burning, pain or a marked colour change, do not assume that it is only a cycle-related change.
- Ovulation: Discharge is often clearer, wetter, more slippery and easier to stretch.[3]
- Before or after a period: Some women notice a different amount or texture, and the pattern may not be identical every cycle.[1]
- Pregnancy: Discharge is often more noticeable than before pregnancy. Healthy discharge is usually thin, clear or milky white and does not have an unpleasant smell.[4]
- Sexual arousal, sexual activity or hormonal contraception: These may also increase the amount of discharge.[1][3]
Do not use an online “cycle discharge timeline” as a diagnostic tool. Cycle length, contraception, pregnancy, perimenopause and individual differences can all affect what you observe.
Vaginal discharge colour, texture, odour and symptoms
This guide is designed to help you decide what to do next. It cannot diagnose the cause. Different conditions can have overlapping symptoms, and a doctor may need to review your history, examine you and test a sample before making a diagnosis.[5][6]
| What you notice | What it may mean | Other signs to watch | Suggested next step |
|---|---|---|---|
| Clear or white | Often within the normal range | No strong odour, itching or pain | Compare with your usual pattern |
| Clear, wetter, slippery or stretchy | May occur around ovulation | No other discomfort | Usually no special treatment is needed |
| White, thick or cottage cheese-like | May occur with vulvovaginal candidiasis, but appearance cannot confirm it | Vulval itching, redness, burning or pain during sex | Arrange a medical assessment and avoid prolonged self-treatment |
| Grey-white and thin, with a strong fishy or musty odour | May be associated with bacterial vaginosis | Itching, irritation or burning during urination; some people have no symptoms | See a doctor for assessment and any necessary tests |
| Yellow, green or frothy | May be associated with an infection or a sexually transmitted infection | Odour, itching, painful urination or pain during sex | Seek medical care promptly rather than relying on cleansing |
| Blood-stained discharge or bleeding between periods | There are several possible causes; infection, cervical polyps and other conditions may need to be excluded | Pelvic pain, bleeding after sex, or any bleeding during pregnancy | Seek medical care promptly; contact a healthcare professional immediately during pregnancy |
What can cause changes in vaginal discharge?
1 | Normal physiological and hormonal changes
Ovulation, the menstrual cycle, pregnancy, sexual arousal and some forms of contraception may change the amount or texture of discharge. If there is no unusual odour, itching, burning, pain or abnormal bleeding, and the change is close to your usual pattern, it is generally reasonable to observe it first.
2 | Vulvovaginal candidiasis
Vulvovaginal candidiasis may cause thick, white, cottage cheese-like discharge together with vulval itching, redness, burning or soreness. However, the US Centers for Disease Control and Prevention notes that these symptoms are not specific, so appearance alone cannot confirm candidiasis.[5]
3 | Bacterial vaginosis (BV)
BV may cause unusual discharge, a strong fishy or musty odour, itching, irritation or burning during urination. Some people have no obvious symptoms. Diagnosis usually involves a clinical history and examination and may include testing vaginal fluid; it cannot be made from colour or odour alone.[6]
4 | Sexually transmitted infections and other infections
Yellow, green or frothy discharge, especially with painful urination, pain during sex, pelvic pain, an unusual odour, sores or blisters, may be associated with trichomoniasis or another sexually transmitted infection. Many infections have overlapping symptoms and some cause no symptoms, so appropriate testing is important.
5 | Other gynaecological and non-infectious causes
Hong Kong’s Centre for Health Protection notes that discharge changes may also be associated with cervical polyps, cervical disease, tampon use and other non-infectious conditions.[1] Seek a medical assessment if discharge is blood-stained, bleeding occurs after sex, changes keep returning or pelvic pain is present.
What can you do now?
- Compare the discharge with your usual pattern. Note its colour, odour, texture, amount, timing and any accompanying symptoms.
- If the amount has increased briefly without other discomfort, consider whether it matches ovulation, your cycle, pregnancy or sexual arousal.
- Clean the vulva only. Warm water is suitable; if there is no irritation, you may choose a gentle, fragrance-free cleanser and pat the area dry afterwards.[2][3]
- Avoid vaginal douching, scented sprays, deodorising products, fragranced wipes, and placing herbs or other products inside the vagina.[1][2][3][6]
- If there are warning signs or symptoms persist or recur, do not rely on online images, self-medication or supplements in place of an assessment.
When should you seek medical care?
Contact a registered doctor, gynaecologist or sexual health service promptly if any of the following occurs:
- The amount increases suddenly, or the discharge becomes grey-white, yellow, green or blood-stained.
- There is a strong fishy, foul or clearly different odour.
- There is vulval or vaginal itching, burning, redness, swelling, pain, sores, blisters or growths.
- You have painful or frequent urination, pain during sex, pelvic pain, bleeding between periods or bleeding after sex.
- Symptoms continue after self-treatment or return soon after treatment.
- During pregnancy, there is an unusual odour, yellow or green discharge, itching, painful urination or any vaginal bleeding.[4]
- You also have a fever, severe lower abdominal pain or feel significantly unwell.
If you are concerned about a sexually transmitted infection, contact the Social Hygiene Service of the Hong Kong Department of Health. Its clinics provide confidential assessment, treatment and counselling.[1]
Four common myths about vaginal discharge
Myth 1 | Discharge means you are not clean
Discharge is a normal bodily function. The aim is not to make the vagina “completely discharge-free”, but to understand your normal pattern and recognise unusual changes.
Myth 2 | Colour alone can identify the infection
Colour, texture and odour provide clues only. Symptoms of candidiasis, BV and sexually transmitted infections can overlap, and an accurate diagnosis may require an examination and tests.
Myth 3 | Cleansing more often will fix it
Vaginal washing, douching and scented products may cause irritation. The World Health Organization also lists vaginal cleansing, douching and inserting products into the vagina among factors associated with BV risk.[6]
Myth 4 | Probiotics can treat cottage cheese-like discharge
Abnormal discharge should not be managed with supplements alone. The CDC states that there is no substantial evidence supporting probiotics as a treatment for vulvovaginal candidiasis.[5]

Frequently asked questions
Q1 | Does an increase in vaginal discharge always mean an infection?
No. Discharge may increase around ovulation, before or after a period, during pregnancy, with sexual arousal or when using some forms of contraception. Seek medical advice if there is also an unusual odour, colour change, itching, burning, pain or abnormal bleeding.
Q2 | What is discharge usually like around ovulation?
Many people notice clearer, wetter, more slippery or stretchier discharge around ovulation. Cycle patterns vary. If there is also an unusual odour or discomfort, do not assume that ovulation is the only cause.
Q3 | Does white, cottage cheese-like discharge always mean candidiasis?
No. This appearance together with itching, redness or burning may occur with candidiasis, but the symptoms are not specific and a diagnosis cannot be made from an image or appearance alone.
Q4 | Should I see a doctor for yellow or green discharge?
Yes. Hong Kong’s Centre for Health Protection lists grey-white, yellow, green and blood-stained discharge among changes that need attention. Seek an assessment promptly if there is also an unusual odour, painful urination or pelvic pain.
Q5 | Is a mild smell from discharge normal?
A mild natural odour can be present. What matters is whether it suddenly becomes stronger, unpleasant or different from your usual pattern. A strong fishy or foul smell, especially with other symptoms, should be assessed.
Q6 | Should I use an intimate wash inside the vagina?
No. The vagina is self-cleaning, and everyday cleansing should focus on the vulva. Avoid douching, scented sprays and deodorising products. If the area is already irritated, water alone is sufficient.
Q7 | Can probiotics improve abnormal vaginal discharge?
Abnormal discharge can have several causes, and probiotics should not replace diagnosis or treatment. The CDC also states that there is no substantial evidence supporting probiotics as a treatment for vulvovaginal candidiasis.
