Discharge during pregnancy is something almost everyone experiences, and most of the time it’s a completely normal sign that your body is doing exactly what it should. Knowing what’s typical, and which changes are worth flagging to a midwife, can save a lot of unnecessary worry.
What Is Normal Discharge During Pregnancy?
Increased vaginal discharge, medically known as leukorrhea, is common throughout pregnancy due to rising oestrogen levels and increased blood flow to the pelvic area. Normal discharge is usually thin, milky white or clear, and mild-smelling. It tends to increase as pregnancy progresses, partly because the body produces more cervical mucus to help protect against infection as the cervix softens in preparation for birth.
Changes by Trimester
- Early pregnancy — discharge often increases due to rising hormone levels, sometimes even before a missed period.
- Second trimester — discharge typically continues at a steady, slightly increased level compared to before pregnancy.
- Third trimester — discharge may thicken and increase further, and near the end of pregnancy you may notice the mucus plug — a thicker, jelly-like discharge that can be tinged pink or brown, often a sign labour may be approaching, though it can happen days or weeks before labour starts.
When Discharge May Signal a Problem
Certain changes in colour, texture, or smell can indicate infection or other issues that are worth checking with a midwife or GP:
- Green or yellow discharge, especially with an unpleasant smell, may indicate a bacterial infection such as bacterial vaginosis or, less commonly, an STI.
- Thick, white, cottage-cheese-like discharge with itching or soreness often points to thrush, which is common during pregnancy due to hormonal changes affecting vaginal pH.
- Pink or brown discharge can be linked to normal changes like implantation or a sensitive cervix after intercourse, but can occasionally signal something that needs checking, especially if accompanied by cramping.
- Watery discharge that keeps coming, particularly before your due date, could indicate leaking amniotic fluid and should be checked promptly.
- Any discharge with blood, especially in larger amounts, or with pain should always be reported to your midwife or maternity unit without delay.
Common Causes of Abnormal Discharge
Thrush and bacterial vaginosis are the two most common causes of unusual discharge in pregnancy, and both are generally treatable with medication that’s safe to use while pregnant. Hormonal shifts make the vagina’s natural pH more prone to imbalance, which is part of why these infections are more common during pregnancy than at other times.
Practical Tips
- Wear breathable cotton underwear and avoid tight synthetic fabrics that trap moisture.
- Avoid douching or using scented soaps and washes internally, which can disrupt natural pH balance.
- Use panty liners rather than tampons to manage discharge, since tampons aren’t recommended during pregnancy.
- Keep track of any changes in colour, consistency, or smell so you can describe them clearly if you need to contact your midwife.
FAQs
Is it normal to have more discharge in early pregnancy?
Yes, increased discharge is one of the earlier changes many people notice, driven by rising oestrogen levels shortly after conception.
What does discharge before labour look like?
Often thicker and jelly-like, sometimes tinged pink or brown — this is commonly the mucus plug, though its loss doesn’t always mean labour is imminent.
Should I call my midwife about unusual discharge?
Yes, if discharge changes colour, develops a strong odour, comes with itching or soreness, or if you notice any bleeding — these are worth checking rather than waiting out.
