Pregnancy is a time of incredible change. Your body is doing amazing things to grow and protect your baby, and with that comes a range of new sensations, some exciting, some unexpected. One common change many women notice is an increase in vaginal discharge.
It can raise plenty of questions: Is it normal? Should I be worried? What does it mean if the colour or smell changes? Understanding what’s normal and what’s not can help you feel more confident and at ease.
Vaginal discharge is usually a healthy sign that your body is protecting itself from infection. However, it can sometimes signal that something isn’t quite right, especially if you experience smelly discharge during pregnancy or a noticeable change in texture or colour.
In this guide, we’ll explain what’s normal, when to get medical advice, and how to stay comfortable throughout your pregnancy journey.
1. Understanding Vaginal Discharge During Pregnancy
Vaginal discharge, known medically as leukorrhoea, is completely normal. It’s your body’s way of keeping the vaginal area clean and protected. The discharge is made up of old cells, healthy bacteria, and fluids produced by your cervix and vaginal walls.
During pregnancy, your hormone levels, especially oestrogen, rise significantly, and blood flow to the pelvic area increases. This naturally leads to more discharge. You might notice a clear or white, milky fluid that can make your underwear feel slightly damp.
This discharge helps:
- Flush out bacteria and prevent infections.
- Keep the vagina clean and balanced.
- It forms part of the mucus plug, which protects your womb from harmful bacteria.
So, while it might feel unusual at first, it’s usually a healthy sign that your body is doing its job.
2. What Normal Discharge Looks and Feels Like
Every woman’s body is unique, but during pregnancy, normal discharge typically has these features:
- Colour: Clear, white, or slightly milky.
- Texture: Thin, smooth, and slippery, similar to egg whites.
- Smell: Mild or odourless.
- Amount: Can increase gradually, especially as your pregnancy progresses.
You might notice a bit more discharge after exercise, intercourse, or later in pregnancy when your body starts preparing for labour.
3. When to Expect Changes
As your due date approaches, vaginal discharge may thicken as your body prepares for birth. Near the end of pregnancy, some women notice a jelly-like mucus with streaks of blood, often
called a “bloody show”, which usually means labour could be starting soon.
However, not every change is normal. Some types of discharge may point to infection or other concerns, so it’s important to know what to look out for.
4. Warning Signs: When Discharge Needs Attention
Here are a few signs that your discharge might need checking by a midwife or GP:
- Strong or Unpleasant Odour
If you notice smelly discharge during pregnancy, especially with a fishy or musty odour, it could be a sign of bacterial vaginosis or another infection.
2. Green, Yellow, or Grey Colour
Normal discharge shouldn’t be strongly coloured. Green, yellow, or grey discharge may suggest an infection such as trichomoniasis or bacterial vaginosis.
3. Thick, Lumpy, or Cottage Cheese-Like Texture
This often points to thrush, a yeast infection that’s common in pregnancy. It may come with itching or irritation, but it’s easily treatable once diagnosed.
4. Pain, Itching, or Burning
If you feel pain or a burning sensation, especially when urinating, get checked as soon as possible. It could be a urinary or vaginal infection.
5. Blood-Stained or Brown Discharge
Light spotting can be normal, especially early on or after intercourse. But heavy bleeding or ongoing brown discharge could indicate a more serious issue, like a placental problem.
Always contact your healthcare provider if you’re unsure.
6. Watery Discharge Late in Pregnancy
A sudden gush or steady trickle of watery fluid could mean your waters have broken. If this happens before 37 weeks, contact your maternity unit straight away.
5. Common Causes of Abnormal Discharge
Here are some of the most common causes behind abnormal discharge in pregnancy:
- Bacterial Vaginosis (BV): Often has a greyish colour and a fishy smell.
- Thrush: Causes thick, white discharge and itching.
- Sexually Transmitted Infections (STIs): Such as trichomoniasis or chlamydia, which may cause yellow or green discharge.
- Urinary Tract Infection (UTI): May cause cloudy discharge or discomfort while urinating.
If you think something might be wrong, avoid self-diagnosing or using over-the-counter treatments without advice. Always speak to your GP or midwife for safe, pregnancy-friendly care.
6. How to Manage Normal Discharge During Pregnancy
Even when discharge is normal, it can sometimes feel uncomfortable. Here are some simple ways to stay fresh and confident:
- Wear breathable cotton underwear to reduce moisture.
- Change underwear if it feels damp.
- Avoid perfumed soaps, sprays, or douches; they can upset your body’s natural balance.
- Use unscented panty liners if needed, but never tampons during pregnancy.
- Stay hydrated and eat a balanced diet to support your immune system.
- Always wipe front to back after using the toilet to prevent infections.
These little habits can go a long way in keeping your vaginal health balanced and comfortable.
7. The Link Between Discharge and Pregnancy Progress
Changes in discharge can sometimes reflect what’s happening in your pregnancy. For example, an increase in clear, thin discharge might simply mean your body is preparing for labour. However, if discharge becomes watery or blood-stained before 37 weeks, it could be a sign of preterm labour.
Keeping an eye on these changes, along with regular check-ups and scans, helps ensure everything is progressing well. Many mums-to-be find extra reassurance through private scans, such as a 4D scan at 14 weeks pregnant, which lets you see your baby’s development in more detail while checking their wellbeing.
8. When to Call Your Midwife or GP
Contact your midwife or GP immediately if you:
- Notice a change in colour, smell, or texture of discharge.
- Experience pain, itching, or burning sensations.
- See blood or brown discharge.
- Have watery discharge that could indicate leaking amniotic fluid.
- Feel unwell, feverish, or have abdominal pain.
Remember, it’s always better to ask and be reassured than to worry or ignore something that feels off.
Final Thoughts
Vaginal discharge during pregnancy is a completely natural part of your body’s way of keeping both you and your baby healthy. Most of the time, there’s no need to worry. However, any sudden changes in colour, smell, or texture deserve attention to rule out infection or other concerns.
