Pregnancy brings many changes to a woman's body. One of the common changes that many expectant mothers notice is an increase in vaginal discharge.
In most cases, increased vaginal discharge during pregnancy is normal and is a result of hormonal changes. However, changes in the colour, smell, consistency or amount of discharge may sometimes indicate an infection or another condition that needs medical attention.
Understanding the difference between normal pregnancy discharge and unusual discharge can help you know when to consult your gynecologist.
Is Vaginal Discharge Normal During Pregnancy?
Yes. Increased vaginal discharge is common during pregnancy.
This discharge is often called leukorrhea. Increased estrogen levels and greater blood flow to the vaginal area can lead to more discharge during pregnancy.
Normal pregnancy discharge is generally:
- Thin or slightly thick
- Clear or milky white
- Mild-smelling or without a strong odour
- Not associated with itching, burning or pain
This normal discharge is part of the body's natural way of maintaining vaginal health and protecting against infections.
What Does Normal Pregnancy Discharge Look Like?
Normal discharge may increase as pregnancy progresses. It can sometimes become more noticeable during the second and third trimesters.
If the discharge is clear or milky white, has no strong unpleasant smell and does not cause itching or irritation, it is usually not a cause for concern.
However, every pregnancy is different. If you notice a sudden or unusual change, it is better to discuss it with your gynecologist.
When Can Vaginal Discharge Be a Sign of an Infection?
Certain changes in vaginal discharge may indicate an infection.
1. White Discharge With Itching
Thick, white discharge that resembles cottage cheese and is associated with itching or irritation may be caused by a yeast infection.
Pregnancy-related hormonal changes can increase the risk of vaginal yeast infections.
2. Yellow or Green Discharge
Yellow or green discharge, particularly when accompanied by an unpleasant smell, itching or pain while urinating, may indicate an infection and should be evaluated by a doctor.
3. Greyish Discharge With an Unpleasant Smell
A thin greyish or whitish discharge with a strong or unusual smell may be associated with bacterial vaginosis.
Pregnant women with symptoms of vaginal infection should consult their gynecologist for appropriate diagnosis and treatment.
4. Discharge With Blood
Pink, brown or blood-stained discharge during pregnancy should not be ignored.
Although light spotting can sometimes occur for different reasons, bleeding during pregnancy needs medical evaluation, particularly when it is heavy or associated with abdominal pain or cramps.
How Can You Tell if It Could Be Amniotic Fluid?
Towards the later stages of pregnancy, it can sometimes be difficult to distinguish between normal vaginal discharge and leaking amniotic fluid.
Amniotic fluid is generally clear or pale and watery and may continue to leak rather than appearing as a small amount of discharge.
If you notice a sudden gush of fluid or continuous watery leakage from the vagina, contact your doctor or maternity care team promptly, as it may indicate that the water has broken.
When Should You Consult a Gynecologist?
Contact your gynecologist if you experience:
- Yellow, green or grey vaginal discharge
- Strong or unpleasant-smelling discharge
- Thick discharge with severe itching
- Burning while urinating
- Vaginal or pelvic pain
- Blood-stained discharge
- A sudden increase in watery discharge
- Continuous leakage of clear fluid
- Fever along with unusual discharge
- Abdominal pain or regular contractions along with discharge
Timely evaluation can help identify infections or other pregnancy-related concerns and allow appropriate treatment.
Can Vaginal Infections Affect Pregnancy?
Some vaginal infections can cause complications if they are left untreated during pregnancy. Therefore, unusual discharge, itching, burning or an unpleasant smell should not be ignored.
Your gynecologist can determine the cause through a clinical examination and, when required, laboratory tests.
Do not self-medicate during pregnancy. Medicines, including vaginal creams or antibiotics, should be used only after consulting your doctor.
How Is Abnormal Vaginal Discharge Diagnosed?
Your gynecologist may ask about:
- The colour and consistency of the discharge
- Any unusual smell
- Itching or irritation
- Pain or burning while urinating
- Abdominal or pelvic pain
- Your stage of pregnancy
- Any previous history of vaginal infections
Depending on your symptoms, your doctor may recommend an examination or testing to identify an infection and determine the appropriate treatment.
What Can You Do to Maintain Vaginal Hygiene During Pregnancy?
Some simple measures can help maintain vaginal hygiene:
- Keep the genital area clean and dry.
- Wear comfortable, breathable cotton underwear.
- Change damp or sweaty clothes promptly.
- Avoid scented vaginal washes, sprays and harsh soaps.
- Avoid douching.
- Do not use medicines for vaginal infections without medical advice.
- Attend your scheduled antenatal check-ups.
Conclusion
Increased vaginal discharge is a common part of pregnancy and is often completely normal. Clear or milky-white discharge without a strong smell, itching or pain is generally less concerning.
However, discharge that changes colour, develops a strong odour, causes itching or pain, contains blood, or becomes suddenly watery should be evaluated by a gynecologist.
