## Quick answer

Brown discharge is usually old blood that has taken longer to leave the body, so it is common at the start or end of a period. Hormonal contraception, ovulation and early pregnancy can also cause brown spotting. If it keeps happening between periods, after sex or after menopause, or comes with itching or a smell, get it checked.

- Brown discharge is usually old blood, common at the start or end of a period.
- Contraception, ovulation and early pregnancy can also cause brown spotting.
- Repeated spotting between periods, after sex or after menopause should be checked.

Brown [discharge](https://splash.care/learn/body-literacy/discharge-decoded) is usually old blood. Blood turns brown as it is exposed to air and takes longer to leave the body, which is why it often appears at the very start or end of a period. On its own, without itching, a bad smell or pain, it is usually nothing to worry about.

## Why do I have brown discharge before my period?

- **Your period is starting slowly:** the first blood can be brown before it turns red.
- **Hormonal contraception:** [spotting](https://splash.care/learn/glossary/spotting) is common, especially in the first few months.
- **Around ovulation:** a little [spotting](https://splash.care/learn/cycle-basics/spotting-between-periods) can happen mid-cycle.
- **Early pregnancy:** light pink or brown [Implantation bleeding](https://splash.care/learn/glossary/implantation-bleeding) can happen around when a [period is due](https://splash.care/tools/period-calculator).

## Why do I have brown discharge after my period?

At the end of a period, flow slows down and the last bit of blood leaves more slowly, so it looks brown. This can last a day or two and is normal.

## When is brown discharge a sign of something else?

Table: Discharge changes worth noting

| What you notice | Possible reason | What to do |
| --- | --- | --- |
| Brown at the start or end of a period | Old blood | Nothing, unless it changes |
| Brown between periods, again and again | Contraception, polyps, infection or cervical changes | See a GP or sexual health clinic |
| Brown or bloody after sex | Irritation, infection or cervical changes | Get it checked |
| Discharge with a fishy smell, itching or soreness | BV, thrush or an STI | Pharmacist, GP or sexual health clinic |
| Any bleeding after menopause | Needs checking | See a GP |

> **Splash says:** log brown spotting as “spotting”, not as your period start, so your cycle length stays honest.

### When to see a doctor

The NHS advises getting bleeding between periods or after sex checked by a GP or sexual health clinic, and any bleeding after menopause. Get urgent advice if you could be pregnant and have bleeding with tummy pain, or bleeding with a high temperature.
