What does watery discharge mean in teens?

Is watery discharge normal during puberty?

Periods & hormones

Updated February 25, 2026

Medically reviewed by Dr. Katie Knight

What does watery discharge mean?

Watery discharge is usually a normal and healthy part of vaginal health.

 It helps keep the vagina clean and balanced, and it often changes at different points in the menstrual cycle.

 If watery discharge comes with itching, irritation, or a strong smell, it should be checked by a healthcare professional.

Watery discharge is typically clear, thin, and slippery.

Many teens notice it increases around ovulation or during hormonal changes in puberty.

On its own, it is usually not a sign of infection.

What does it mean when a girl’s discharge is watery?

Watery discharge usually means the body is producing healthy vaginal fluid to keep the area clean and protected.

 It is common during puberty and at certain points in the menstrual cycle, especially around ovulation.

For most teens, this is a normal hormonal response.

Watery discharge can:

  • Increase as hormones rise during puberty
  • Appear around ovulation (mid cycle)
  • Look clear or slightly milky
  • Feel thin or wet rather than sticky

Watery discharge is usually not linked to infection unless other symptoms are present.

It can sometimes feel surprising when your teen is still getting used to body changes, but it is usually a healthy sign.

Is watery discharge normal before a period?

Yes, watery discharge before a period can be normal.

Hormone levels change in the second half of the menstrual cycle, and discharge may shift in texture and amount before bleeding begins.

Many teens notice natural variation at this stage.

It is common for discharge to:

  • Change texture during the month
  • Vary in amount
  • Feel wetter at some stages

These patterns are part of a healthy menstrual cycle.

Tracking changes over time can help teens learn what is typical for their body.

When should a parent worry about watery discharge?

Watery discharge should be checked by a family doctor if it is unusual for your teen or comes with symptoms that may suggest irritation or infection.

Colour, smell, and comfort usually matter more than the amount of discharge.

Seek medical advice if there is:

  • A strong or unpleasant odour
  • Itching, burning, or redness around the vagina
  • Pain when urinating
  • Green, yellow, or grey discharge
  • Fever or feeling generally unwell

If you're unsure, it is always reasonable to get medical reassurance.

Does watery discharge mean a first period is coming?

Discharge can begin months or even years before a teen’s first period.

It is often one of the early signs that puberty has started and the body is preparing for menstruation.
However, it does not mean a period will start immediately.

This happens because rising oestrogen stimulates the body to produce vaginal fluid.

This discharge:

  • Is usually clear, white, or watery
  • Has little or no smell
  • May come and go at first

Some teens notice discharge for a long time before their first period, while others start bleeding sooner.
Everyone develops at their own pace.

What should parents know about watery discharge?

Watery discharge is usually a normal part of puberty and the menstrual cycle.

For most teens, it is a healthy sign of hormonal development rather than a problem.

What matters most is whether there are additional symptoms or discomfort.

Open, calm conversations help teens feel confident asking questions and speaking up if something changes.

If your teen feels uncomfortable or something seems unusual, checking with a doctor can provide reassurance.
