The truth about increased vaginal discharge in pregnancy

In short: More vaginal discharge is normal in pregnancy. Thin, milky white or clear discharge with a mild smell, called leukorrhea, helps keep the vagina clean and often increases towards the third trimester. Call your doctor if the discharge turns yellow, green or grey, smells strong or fishy, is thick and clumpy, or comes with itching or burning. Go to hospital straight away for watery fluid that soaks a pad or for heavy bleeding.

Pregnancy comes with a lot of changes that no one really prepares you for. One of the most common, and least openly discussed, is increased vaginal discharge.

If you have noticed your underwear staying damp or are worried about whether what you see is normal, you are not alone. Almost every pregnant woman will experience some change in vaginal discharge at some point. But knowing the difference between normal and abnormal discharge can help you feel more confident and know when to call your doctor.

This guide breaks down what is typical, what could be a sign of infection or complications, and how to stay comfortable.

What is normal vaginal discharge during pregnancy?

During pregnancy, your body produces more estrogen and increases blood flow to your pelvic area. This leads to a rise in vaginal secretions known as leukorrhea, a thin, milky white discharge with a mild smell.

This discharge helps:

• Keep your vagina clean
• Prevent infections by flushing out bacteria
• Maintain a healthy balance of good bacteria

You might notice: More discharge than before pregnancy Thin, white, or clear fluid Mild, non-offensive odour

Many women find that the amount increases as pregnancy progresses, especially in the third trimester. Some even feel like they are “leaking” constantly, it is completely normal.

When discharge might be a problem

While most discharge is harmless, certain changes can be signs of infection or other issues. Watch out for these warning signs:

Color changes

• Yellow or green discharge
• Greyish tint

Strong or foul odor

• Fishy smell (often linked to bacterial vaginosis)
• Yeasty smell (could mean a yeast infection)

Texture and accompanying symptoms

• Thick, cottage cheese-like discharge
• Itching, burning, swelling, or redness

Watery fluid that soaks a pad

• Could be amniotic fluid leaking at any stage of pregnancy; contact your hospital straight away

Bloody discharge

• Light spotting can be normal after sex or an exam, but heavier bleeding should always be checked right away

If you notice any of these symptoms, contact your healthcare provider. It is better to ask and get reassurance than to worry.

Common causes of abnormal discharge in pregnancy

Some infections are more common during pregnancy:

Yeast infections (candidiasis)

• Thick, white, clumpy discharge
• Severe itching

Bacterial vaginosis (BV)

• Thin, grey discharge with a strong odor

Trichomoniasis

• Frothy yellow-green discharge
• Itching and discomfort

Leaking amniotic fluid

• Watery fluid that does not stop
• Usually, odorless

Proper diagnosis and treatment are essential to protect you and your baby’s health.

How to manage increased vaginal discharge

While you cannot stop your body from making discharge (nor should you), you can stay comfortable:

Wear breathable cotton underwear Change underwear or use unscented panty liners (avoid tampons) Keep the area clean with mild soap and water Avoid douching or using scented washes,these disrupt your vaginal flora

When to call your doctor

• You notice sudden changes in color, smell, or consistency
• You have pain, burning, or itching
• You suspect your water has broken
• You experience heavy bleeding (go to hospital straight away)

Remember, there is no such thing as a silly question in pregnancy.

Increased vaginal discharge during pregnancy is usually just your body’s way of protecting itself and preparing for birth. Although it can be uncomfortable, it is one of the most common pregnancy symptoms, and perfectly normal most of the time.

But if you feel something is not quite right, listen to your body. Reach out to your healthcare provider.

Questions women ask

Is white discharge normal in pregnancy?

Yes. Thin, milky white or clear discharge with a mild smell is normal and usually increases as pregnancy goes on. It is caused by higher oestrogen and more blood flow to the pelvic area, and it helps protect you from infection.

What colour discharge is not normal in pregnancy?

Yellow, green or greyish discharge, a strong or fishy smell, or thick, cottage cheese-like discharge can be signs of infection. So can itching, burning, swelling or redness. Tell your doctor, as infections should be properly checked and treated in pregnancy.

How do I know if it is discharge or my water breaking?

Normal discharge is thin and milky. Leaking amniotic fluid is watery, usually has no smell, keeps coming and can soak a pad. If you think your water may have broken, contact your doctor or hospital straight away.

When should I get checked urgently?

Go to hospital straight away if you have watery fluid soaking a pad, heavy bleeding, severe tummy pain, or if your baby is moving less than usual. See a doctor the same day for fever. Light spotting after sex or an examination can happen, but heavier bleeding always needs checking right away.

How can I stay comfortable with more discharge?

Wear breathable cotton underwear and change it or use unscented panty liners when needed. Avoid tampons. Wash the outer area with mild soap and water, and do not douche or use scented washes, as these upset the natural balance.
