Pregnancy is a journey filled with many changes—some expected and others that can take you by surprise. As your baby grows, so does your awareness of how your body is adjusting to support new life. One common symptom that many women experience, especially in the later stages of pregnancy, is an increase in vaginal discharge. It may feel unusual or even worrying at first, but in most cases, it’s completely normal and part of the body’s natural process.
From early symptoms like morning sickness and tiredness to those memorable baby scans at 12 weeks, every part of pregnancy brings a new milestone. As you enter the third trimester, your body is preparing for birth, and one of the signs of that preparation is increased discharge. In this article, we’ll explore why this happens, what’s considered normal, what to look out for, and how to stay comfortable in those final weeks before baby arrives.
What Is Vaginal Discharge?
Let’s start with the basics. Vaginal discharge is a fluid that helps keep the vagina clean and free from infection. It’s made up of natural secretions from the cervix and vaginal walls, along with old cells and friendly bacteria. Discharge is completely normal throughout a woman’s life, and it changes in colour, texture, and amount depending on the time of the month and hormonal shifts.
During pregnancy, your body produces more discharge than usual. This is due to rising hormone levels—especially oestrogen—and increased blood flow to the pelvic area. It’s your body’s way of keeping the reproductive system healthy and creating a safe environment for your growing baby.
Why Discharge Increases in the Third Trimester?
As you move into the final stretch of pregnancy, you might notice that your discharge becomes heavier or more frequent. There are several reasons for this increase, all of which relate to how your body is preparing for labour and delivery.
1. Hormonal Changes
Hormones play a big role in every stage of pregnancy. By the third trimester, your oestrogen levels are higher than ever, which stimulates the production of more cervical mucus. This mucus eventually becomes part of the discharge you see.
2. Increased Blood Flow
The amount of blood circulating in your body increases significantly during pregnancy, especially in the pelvic region. This extra blood flow stimulates the glands in the cervix and vagina, causing more discharge to be released.
3. Pressure on the Cervix
As your baby drops lower into your pelvis in the final weeks, the added pressure on the cervix can lead to more discharge. This is often a sign that your body is gearing up for labour.
4. The Mucus Plug
Later in pregnancy, you might notice thick, jelly-like discharge or small bits of what looks like clear or blood-tinged mucus. This could be part of your mucus plug—a protective barrier that seals the cervix during pregnancy. Losing the plug is a normal sign that your body is getting ready for labour, although it doesn’t always mean labour will start immediately.
What Does Normal Discharge Look Like?
Understanding what’s normal can help you feel more at ease and avoid unnecessary worry. In the third trimester, healthy discharge usually has the following features:
- Colour: Clear, white, or slightly creamy
- Smell: Mild or odourless
- Texture: Thin, watery, or slightly sticky
- Amount: Increased compared to earlier trimesters
This type of discharge is usually nothing to worry about. It may feel a bit inconvenient, but it’s a positive sign that your body is doing what it needs to do to protect both you and your baby.
When Should You Be Concerned?
Although increased discharge is usually normal, certain signs suggest it’s best to speak to your midwife or GP. You should get checked if you notice any of the following:
- Discharge that’s green, yellow, or grey
- A strong or unpleasant smell
- A thick, clumpy texture (like cottage cheese)
- Itching, redness, or a burning sensation
- Sudden gushes or continuous leaking (could be water breaking)
- Blood in your discharge (before full term)
These signs could point to an infection, such as thrush or bacterial vaginosis, or in some cases, they may signal that labour is beginning earlier than expected. It’s always better to check and feel reassured than to worry in silence.
How to Manage Increased Discharge?
Even though it’s normal, dealing with discharge every day can feel uncomfortable. Luckily, there are a few simple ways to stay clean and fresh throughout the day:
1. Wear Breathable Cotton Underwear
Cotton is soft, absorbent, and lets your skin breathe. Avoid tight-fitting underwear made of synthetic materials, which can trap moisture and increase irritation.
2. Use Unscented Panty Liners
Thin liners can help absorb discharge and keep you dry. Make sure to choose unscented products to avoid irritation or allergic reactions.
3. Avoid Vaginal Douching or Scented Products
The vagina is self-cleaning and doesn’t need washing on the inside. Perfumed soaps, sprays, or wipes can upset the natural balance and lead to infection.
4. Practice Good Hygiene
Wash the outside of your vaginal area with warm water daily and always wipe from front to back after using the toilet. This helps prevent the spread of bacteria.
Is It a Sign of Labour?
Towards the end of the third trimester, some changes in discharge may be an early sign that labour is on the horizon. These include:
- Losing your mucus plug, which may look like thick, jelly-like mucus, sometimes tinged with blood (known as a “bloody show”).
- A sudden increase in discharge, especially if it’s watery—this might be your waters breaking.
If you think your waters have broken or you’re having regular contractions, contact your maternity unit right away.
Emotional Support During the Third Trimester
By the third trimester, you’re likely feeling a mix of emotions—excitement, impatience, and maybe a bit of anxiety. Physical symptoms like discharge, back pain, or fatigue can add to the overwhelm. This is the time to slow down, rest more, and take care of both your body and mind.
Don’t hesitate to reach out for support—whether it’s your midwife, your partner, or fellow parents going through the same journey. Talking about changes like discharge might feel awkward at first, but it’s completely natural and often reassuring once you realise just how common it is.
Final Thoughts
Increased discharge during the third trimester is usually just another way your body is preparing for the arrival of your baby. It’s a healthy, natural part of pregnancy, even if it’s not the most talked-about symptom.
Understanding what’s normal and what’s not can give you peace of mind and help you feel more in control during the final weeks. And as you move closer to meeting your baby, remember how far you’ve come—from early signs to baby scans at 12 weeks, and now this final stage before birth.
Pregnancy may be filled with surprises, but with the right information and support, you can approach each stage with confidence and calm.
