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.

- Repeated spotting between periods, after sex or after menopause should be checked.
Brown discharge 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 is common, especially in the first few months.
- Around ovulation: a little spotting can happen mid-cycle.
- Early pregnancy: light pink or brown implantation bleeding can happen around when a period is due.
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.
