discharge changes.
last revised · reviewed 2026-07-05
More vaginal discharge than usual is normal throughout pregnancy — healthy discharge is clear or milky white, mild-smelling, and increases as pregnancy progresses. Changes in colour, smell, or texture, or any blood, are the signals worth reporting to your midwife or doctor.
what it feels like
A noticeable increase in thin, milky-white or clear discharge (leukorrhoea) from early pregnancy, often enough to want a panty liner by the third trimester. Near the end, discharge may thicken further and eventually include the mucus plug — jelly-like, sometimes blood-streaked.
why it happens
Rising oestrogen increases blood flow to the vagina and cervix and steps up mucus production. This extra flow is protective: it maintains healthy vaginal bacteria and forms a barrier — including the mucus plug sealing the cervix — that helps keep infection away from the womb.
what helps
- Unscented panty liners keep you comfortable — change them regularly
- Wash with water or a mild, unperfumed wash; the vagina cleans itself and needs no help inside
- Never douche — it disrupts the protective bacterial balance and raises infection risk
- Cotton underwear, changed daily, keeps the area dry and healthy
- Wipe front to back
- Avoid perfumed bath products and vaginal deodorants
- Know your normal — noticing a change early is the most useful thing you can do
when to call your midwife or doctor
- Discharge that is green, grey, or yellow, frothy, or smells fishy or foul — likely infection, which is treatable; call your midwife or doctor
- Thick white discharge with itching or soreness — probably thrush; get pregnancy-safe treatment via your midwife, doctor, or pharmacist rather than self-treating
- A sudden gush or continuous trickle of watery fluid — possible waters breaking; call your maternity unit whatever your gestation
- Any blood in your discharge, at any stage — call your midwife or doctor

common questions
What does normal pregnancy discharge look like?
Thin, clear or milky white, and mild-smelling — and there's more of it than you're used to, increasing as pregnancy progresses. That increase is healthy and protective. Colour changes (green, grey, yellow), strong smells, itching, or blood are the things to report.
Is watery discharge my waters breaking?
Normal discharge is mucus-like; amniotic fluid is watery, clear or slightly pink, and keeps coming — a gush or a steady trickle you can't control. If you suspect your waters have gone at any stage of pregnancy, put on a pad (not a tampon) and call your maternity unit straight away.
Can I treat thrush myself while pregnant?
See your midwife, doctor, or pharmacist first rather than self-treating — the usual choice in pregnancy is a cream or pessary rather than oral tablets, and oral anti-thrush medication is not recommended in pregnancy. Treatment is effective and thrush doesn't harm the baby.
read it in context
Discharge changes tends to show up around these weeks of pregnancy:
related symptoms
- Back pain
Lower back pain affects up to two thirds of pregnant women, usually from mid-pregnancy onwards, as the growing bump shifts your centre of gravity and the hormone relaxin loosens supporting ligaments.
- Bleeding gums
Swollen, tender gums that bleed when brushing affect the majority of pregnant women — pregnancy hormones increase blood flow to the gums and amplify their reaction to plaque.
- Food aversions
Food aversions — a sudden, visceral repulsion to foods you normally enjoy — affect around 6 in 10 pregnant women, usually starting in the first trimester alongside nausea.
