Most people notice their vaginal discharge changes during pregnancy — usually there's simply more of it. This is a normal response to rising hormones and increased blood flow to the area, and on its own isn't something to worry about.
What matters is knowing your own normal, so you can spot the changes that are worth mentioning to your midwife or doctor — particularly changes in colour, smell or texture, or any sign that fluid could be your waters rather than discharge.
What is vaginal discharge in pregnancy?
Vaginal discharge (sometimes called leukorrhea) is the fluid the vagina and cervix normally produce to keep the area clean and free of infection. In pregnancy, rising oestrogen and increased blood flow to the pelvis mean most people produce noticeably more of it, and it often becomes thinner and more frequent as pregnancy progresses.
Normal pregnancy discharge is usually clear or milky-white, thin to slightly thick, and has little or no smell. It's common for it to increase further in the third trimester. None of this needs treatment — it's simply your body's normal response to pregnancy.
More discharge near the end of pregnancy
A noticeable increase in thick, clear or slightly blood-tinged discharge close to your due date can be a sign your body is preparing for labour, sometimes including the loss of the mucus plug.
What affects vaginal discharge in pregnancy?
Discharge changes for a mix of normal pregnancy reasons and, sometimes, infections that are worth treating.
Rising oestrogen
Higher oestrogen levels increase blood flow to the vagina and cervix and boost normal secretions, which is why most people notice more discharge from early pregnancy onwards.
Thrush (vaginal candidiasis)
Pregnancy makes thrush more common. It causes thick, white, cottage-cheese-like discharge with itching, soreness or stinging. It's not harmful to your baby and is easily treatable — check with your doctor or midwife before using any treatment, as not all are suitable in pregnancy.
Bacterial vaginosis (BV)
An imbalance of normal vaginal bacteria can cause thin, grey-white discharge with a strong fishy smell, often more noticeable after sex. It's common, treatable, and worth treating in pregnancy as it's linked with a small increased risk of preterm birth if left unchecked.
Sexually transmitted or other infections
Green, yellow or frothy discharge, sometimes with soreness or pain when passing urine, can indicate an infection such as trichomoniasis or chlamydia, which need testing and treatment.
The mucus plug loosening
As your cervix softens in preparation for labour, you may notice thicker, jelly-like discharge, sometimes streaked with blood (a "show"). This is most relevant from late pregnancy onwards.
Good hygiene helps, but avoid these
- Wash with water alone (or a mild, unperfumed wash) — avoid soap, douches and vaginal deodorants
- Wear cotton underwear and avoid tight synthetic fabrics
- Change out of damp swimwear or gym kit promptly
- Don't use scented panty liners or wipes
When discharge is normal
Increased discharge through pregnancy is expected. It's reassuring when:
- It's clear or milky-white, thin, and doesn't smell strongly.
- There's no itching, soreness or burning.
- The amount gradually increases as pregnancy progresses, especially in the third trimester.
- It doesn't come with pain, fever or bleeding.
| Usually normal discharge | Needs medical attention | |
|---|---|---|
| Colour | Clear or milky-white | Green, yellow, grey, or blood-streaked |
| Texture | Thin, or slightly thick | Thick and clumpy (like cottage cheese), or frothy |
| Smell | Mild or none | Strong, fishy or foul-smelling |
| Symptoms | None | Itching, soreness, burning, or pain passing urine |
| Flow | Gradual and manageable with a liner | A sudden gush or continuous watery trickle |
A panty liner is fine
Using a panty liner to manage normal increased discharge is completely fine. Avoid tampons in pregnancy, and don't use scented products, which can upset the natural balance and trigger irritation.
Warning signs — get checked promptly
Contact your midwife or doctor promptly — or go to your maternity unit straight away for the fluid-related signs below — if you notice:
Seek urgent medical care if you have
- A sudden gush of fluid, or a continuous trickle of watery fluid — this could be your waters breaking, especially urgent before 37 weeks.
- Green, yellow, grey or foul/fishy-smelling discharge.
- Discharge with blood, or any vaginal bleeding.
- Thick, white, itchy discharge with soreness (likely thrush, but still worth confirming and treating safely).
- Pain, burning or stinging when you pass urine.
- Tummy pain, fever, or feeling generally unwell alongside a change in discharge.
If you think your waters may have broken, don't wait — contact your maternity unit straight away, whatever time of day. If you ever notice reduced or absent baby movements, contact your maternity unit the same day too.
A watery gush or trickle needs urgent checking
This can mean your waters have broken. Before 37 weeks this is especially urgent, as it can lead to preterm labour or increase infection risk — go to your maternity unit for assessment straight away.
Self-care for normal discharge
For everyday increased discharge, simple hygiene measures are usually all that's needed.
Everyday hygiene
- Wash the outer genital area with water only, once a day; avoid soap, bubble bath and douching.
- Wipe front to back after using the toilet.
- Change underwear daily, and choose breathable cotton fabrics.
Managing the extra flow
- Use unscented panty liners, changed regularly, rather than tampons.
- Avoid tight-fitting or synthetic underwear, which trap moisture.
- Let the area breathe — cotton underwear and going without underwear at night can help.
If you suspect thrush or BV
- Don't self-treat with over-the-counter remedies without checking with your doctor, pharmacist or midwife first — not all thrush treatments are suitable in pregnancy.
- Avoid perfumed products and douching, which can make imbalances worse.
- Complete any treatment course your doctor prescribes, even if symptoms ease early.
Probiotic yoghurt and loose clothing
Some people find plain probiotic yoghurt and loose, breathable clothing help with recurrent thrush, though evidence is limited. These are safe to try alongside, not instead of, medical advice.
When to consult a doctor or midwife
Book to see your doctor or midwife (rather than waiting for your next routine appointment) if:
- You have itching, soreness or a change in colour, texture or smell that doesn't fit the "normal" description above.
- You think you might have thrush or bacterial vaginosis and want it confirmed and treated.
- You have any pain when passing urine alongside a discharge change.
- Symptoms don't improve after treatment, or keep coming back.
- You're simply unsure whether what you're noticing is normal.
Track changes over time
Logging changes in discharge alongside your other symptoms can help you and your midwife spot patterns quickly.
Open the Pregnancy TrackerFrequently asked questions
Is it normal to have more discharge throughout pregnancy?
Yes. Rising oestrogen and increased blood flow mean most people produce more discharge throughout pregnancy, often increasing further in the third trimester. As long as it stays clear or milky-white with little smell and no itching or soreness, it's a normal part of pregnancy.
How can I tell discharge apart from my waters breaking?
Normal discharge is usually a gradual, manageable amount you notice on a liner. Waters breaking typically causes either a sudden, noticeable gush of watery fluid or a continuous trickle you can't control. If you're at all unsure, contact your maternity unit — they can check quickly and it's always worth asking.
What does thrush discharge look like in pregnancy?
Thrush typically causes thick, white discharge often described as looking like cottage cheese, along with itching, soreness or stinging around the vagina. It's very common in pregnancy, not harmful to your baby, and treatable — but check with your doctor or pharmacist, as not every treatment is suitable in pregnancy.
Can discharge changes mean my waters have broken early?
Yes — a sudden gush or ongoing watery trickle can mean your waters have broken, and this needs urgent assessment, especially before 37 weeks. Contact your maternity unit straight away rather than waiting to see if it happens again.
Is a fishy smell always bacterial vaginosis?
A strong fishy odour, especially with thin grey-white discharge, is the classic sign of bacterial vaginosis, but only a test can confirm it. See your doctor or midwife for a proper diagnosis and treatment, since untreated BV in pregnancy is linked with a small increased risk of preterm birth.
Does normal discharge mean labour is close?
Not on its own. A noticeable increase in thick, jelly-like discharge, especially if blood-streaked (a "show"), can be an early sign labour may be approaching in the final weeks — but many people also have normal discharge changes without labour starting soon. If you're under 37 weeks and notice this, contact your midwife.
