Pregnancy Discharge Colours Complete
Vaginal discharge naturally increases during pregnancy, and its colour and consistency can tell you a lot about whether things are normal or worth checking. This guide breaks down what different discharge colours usually mean and when to get in touch with your midwife or GP.
What's normal in pregnancy
Rising oestrogen and increased blood flow to the pelvic area mean most pregnant people notice more discharge than usual, especially as pregnancy progresses. Normal pregnancy discharge (sometimes called leukorrhoea) is:
- Thin to slightly thick in texture
- White or clear in colour
- Mild-smelling or odourless
- Increasing gradually as pregnancy goes on, with a heavier, more mucus-like discharge sometimes noticed near the end of the third trimester
This is your body's way of protecting the vagina and cervix from infection, and it doesn't need any treatment.
Colours that need a closer look
- Green or yellow — can suggest a bacterial or sexually transmitted infection and should be checked by your GP or midwife
- Grey, watery, with a fishy smell — often points to bacterial vaginosis (BV), which is common and treatable but worth confirming
- Thick, white, and clumpy (like cottage cheese), usually with itching — typically thrush, which is common in pregnancy and can be treated with pregnancy-safe options
- Pink or brown — can be harmless spotting (for example after sex or an internal examination) but should still be mentioned to your midwife, particularly in later pregnancy
- Red or bloody — contact your midwife or maternity unit promptly; this needs assessment, especially if it's more than light spotting
- Watery and gushing or a continuous trickle, particularly from around 37 weeks — could be your waters breaking and needs urgent midwife contact
Looking after yourself day to day
- Wear cotton underwear and change it regularly
- Use unscented panty liners if discharge is heavy — avoid tampons
- Avoid perfumed soaps, douches, or feminine hygiene sprays, which can disrupt your natural balance and increase infection risk
- Wipe front to back after using the toilet
When to contact your midwife or GP
Trust your instincts — if discharge looks, smells, or feels different from your normal, or is accompanied by itching, soreness, pain, or bleeding, it's always reasonable to get it checked. Most causes are straightforward to treat, and catching an infection early protects both you and your baby.
Frequently Asked Questions
What colour discharge is normal in pregnancy?
Thin, white or clear, and mild-smelling discharge is normal and tends to increase throughout pregnancy. It's your body's natural way of keeping the vagina healthy. If the colour, smell, or texture changes noticeably, it's worth mentioning to your GP or midwife.
When should I worry about discharge colour?
Green, yellow, or grey discharge, especially with an unpleasant smell, itching, or soreness, can indicate an infection and should be checked. Any pink, brown, or red discharge — or a sudden watery gush — should also be reported to your midwife promptly.
Can discharge colour tell me if something is wrong with my baby?
Discharge changes are almost always about you — infections, hormonal shifts, or your waters — rather than a direct sign of how your baby is doing. Still, because some causes (like an untreated infection or ruptured membranes) can affect pregnancy, it's always worth getting unusual discharge checked rather than guessing.
