Why does my daughter have brown discharge?

Brown discharge usually indicates old blood leaving the body, and it is a normal part of puberty and the menstrual cycle.

It commonly appears before a first period, at the end of a period, or during hormonal changes when cycles are still settling.

In most cases, it’s nothing to worry about and doesn’t mean something is wrong.

However, if brown discharge comes with pain, itching, burning, or a strong smell, it’s a good idea to speak to a doctor for reassurance.

Brown discharge before a period: is this normal for my daughter?

If your 11 or 12 year old daughter has brown discharge, it’s completely valid to feel concerned – especially if they haven't started their period yet.

Many parents worry that brown discharge means something is wrong, or wonder whether it’s a sign that a first period is coming.

The good news is that brown discharge before a period is usually normal, especially during puberty.

In our app luna, we often hear from teens who have questions about changes in their discharge and what it means for their menstrual health. 

Understanding why it happens and when it’s a sign to check in with a doctor can help your daughter feel more assured about their health.

So here’s a simple breakdown of what brown discharge means, when it’s expected, and when it might be worth paying closer attention.

What does brown discharge mean?

Brown discharge is usually just old blood mixed with vaginal fluids (commonly known as discharge).

When blood takes longer to leave the body, it oxidises (mixes with oxygen) and turns brown instead of red.

This is a natural process and happens to almost everyone who menstruates!

It can occur:

• Before a period: the body is getting ready for menstruation, and some blood might be released slowly, causing it to mix with oxygen and turn brown
• After a period: the uterus is clearing out the last bits of blood, which take longer to leave and so turns brown with time
• Mid-cycle: hormonal changes or ovulation can sometimes cause slight spotting (bleeding between periods) that looks brown as it's very light and flowing slowly

Most of the time, brown discharge is completely normal and part of the body’s natural cycle as it clears out old blood.

However, if it comes with a strong smell, itching, burning, frequent spotting or discomfort, it could indicate an infection or point to other medical conditions that might require further investigation.

Why does my daughter have brown discharge before her first period?

If your teen hasn’t started their first period yet, brown discharge might be a sign that it’s coming soon.

You could explain it like this:

• “Your body is getting ready for your first period – this can happen in the months leading up to it.”
• "It’s just a small amount of blood flowing slowly, which is completely normal.”

Some teens experience brown discharge for weeks or months before their first proper period, while others don’t notice it at all.

Both are completely normal.

If they ask when their first period will come after noticing brown discharge, there’s no exact timeline – it could be soon, or it could take a few more months. 

Reassuring them that everyone’s body develops at its own pace can help ease any anxiety they might have.

Why does my daughter have brown discharge after her period?

Many teens experience brown discharge at the end of their period. 

This happens because the uterus is still shedding the last bits of blood, which takes longer to leave the body and appears brown instead of red.

You could explain it in a simple way such as:

• “It’s just your body finishing up your period – this happens to most people.”
• “The blood is a bit older, which is why it looks brown instead of red.”

If brown discharge lasts more than a few days after their period ends, it could be due to hormonal fluctuations, which are very common in teens as their cycles start to regulate.

When should I worry about brown discharge?

While brown discharge is usually not a cause for concern, there are some cases where it might be worth getting a medical opinion. 

Encourage your teen to let you know if they notice:

• A strong, unpleasant smell along with the discharge (this could indicate an infection)
• Itching, burning, or pain in the vaginal area
• Frequent or unpredictable brown discharge between periods
• Irregular brown discharge can sometimes be linked to:
• Hormonal imbalances – common in teens as their cycle is still regulating
• Infections like bacterial vaginosis or a yeast infection
• Irritation from new period products, scented soaps, or certain fabrics

If your teen is worried, you can remind them that it’s okay to check with a doctor when they are concerned about their wellbeing.

How can I reassure my daughter about brown discharge?

Experiencing brown discharge can be overwhelming for teens, especially the first time. Letting them know that brown discharge is common and happens to almost everyone can help them feel more at ease.

Here are some things you could say:

• "Your body is adjusting to its cycle and it's likely your period is on it's way/ending for the month – this happens to a lot of people."
• “If you’re ever worried, it’s always okay to ask me or luna.”
• “It’s just another way your body takes care of itself – nothing to worry about.”

Keeping the conversation open and normalising the experience helps teens feel more comfortable asking questions and understanding their bodies.

What if my daughter feels embarrassed about brown discharge?

Some teens might feel uncomfortable talking about discharge, even with a parent.

If they seem hesitant, you can:

• Let them know it’s normal: even saying, “I know this can feel awkward, but it’s totally normal and happens to everyone who has periods” can help
• Give them resources: if they don’t want to talk in person, suggest reliable sources like luna!
• Encourage questions at their own pace: sometimes, just letting them know they can ask questions whenever they’re ready helps take the pressure off
