What is Vaginal Discharge in Pregnancy?
An increase in vaginal discharge is normal during pregnancy, caused by rising hormone levels and increased blood flow to the area. Normal pregnancy discharge is usually thin, milky-white, and mild-smelling, and tends to increase as pregnancy progresses.
Changes in colour, consistency, smell, or the presence of blood can indicate something needing attention, from a simple infection like thrush to more significant issues like preterm labour or waters breaking, so it's worth knowing what's expected and what to report.

- 2Wear breathable cotton underwear.This helps maintain a healthy balance and reduce irritation.
- 3Avoid scented products.These can disrupt the natural balance and increase the risk of irritation or infection.
- 4Monitor for changes.Note any change in colour, smell, or amount, and report it to your maternity team.
