Is brown discharge normal?

Often, yes. Brown discharge is usually just a little old blood mixing with normal discharge — see our period blood colour guide for the full picture on brown. See a provider if brown discharge is persistent between periods over several cycles, recurs after sex, smells foul, comes with pelvic pain, or appears after menopause.

What STD causes brown discharge?

Trichomoniasis can irritate the vagina and cervix enough to cause flecks of blood, which turn brown by the time they leave the body. Chlamydia can cause bleeding between periods or after sex. Bacterial vaginosis, which isn't an STI, can also cause greyish or brownish discharge. Many of these cause few other symptoms, so a test is the only way to know.

Does brown discharge mean I'm pregnant?

Not on its own. Brown spotting is far more often old period blood or mid-cycle spotting. It can be implantation bleeding, which tends to be light and short and happens around the time your period is due, but only a pregnancy test can tell you. If your period doesn't arrive, test.

Can a UTI cause brown discharge?

A urinary tract infection doesn't change your vaginal discharge, but it can put blood in your pee, which may look pink, red or brown on toilet paper. If you also have burning when you pee, need to go more often, or your pee is cloudy, see a pharmacist or provider. UTIs are easy to treat.

How do I stop brown discharge?

Normal brown discharge doesn't need stopping: it clears on its own within a few days. If it keeps coming back, the fix depends on the cause, such as a different contraceptive for spotting on birth control, treatment for an infection, or a check for polyps. Douching won't stop it and can irritate the vagina.

Why do I get brown discharge after sex?

A little brown or pink spotting after sex can come from a sensitive area on the cervix (cervical ectropion), small growths called polyps, vaginal dryness, or an infection such as chlamydia. It's usually not serious, but NHS advice is to get bleeding after sex checked by a GP or sexual health clinic.

Brown Discharge

Brown discharge is almost always a small amount of old blood mixed with normal discharge. Blood darkens as it takes longer to leave the body, so brown discharge most often shows up just before or right after a period. It can also appear around ovulation, in early pregnancy, with hormonal birth control, or after sex. Less often it comes from an infection such as trichomoniasis or bacterial vaginosis. After menopause, any bleeding, even a brown smear, needs a check. This page explains what brown discharge means at each point in your cycle, whether it can be an early sign of pregnancy, and when it's worth seeing a provider.

brown discharge — usually normal

Brown discharge is usually just a little old blood mixing with normal discharge — see our period blood colour guide for the full picture on brown.

What brown discharge means

Brown discharge is usually just discharge mixed with a small amount of old blood. Blood turns brown as it oxidises, so brown discharge most often shows up at the very start or end of a period, when old blood is clearing slowly. It can also appear mid-cycle as light ovulation spotting, or — earlier than an expected period — as a touch of implantation spotting in early pregnancy. The occasional brown discharge between periods is common and usually harmless. It becomes worth a closer look if it's persistent across several cycles, happens after sex repeatedly, or comes with pain, an odour, or other symptoms.

When you’ll usually see it

The start or end of a period (old blood clearing)
Mid-cycle as light ovulation spotting
Occasionally as early-pregnancy implantation spotting

To see roughly where today falls in your own cycle, our Menstrual Cycle Calculator maps out the four phases from your last period date.

Brown discharge before your period

A day or two of brown spotting before a period is common. It's often the first slow trickle of blood before your flow picks up. If it lasts several days every cycle, or your pattern changes, mention it to a provider. Bleeding between periods can come from hormonal contraception, small growths such as polyps or fibroids, or an infection like chlamydia, and these are easy to check.

Light brown spotting around the day your period is due can also be implantation bleeding, but you can't tell the two apart by colour. Take a pregnancy test on the day your period is due, or a few days later if the spotting is all you get.

Brown discharge after your period, or two weeks later

At the end of a period, the last of the blood leaves slowly and turns brown, so a few days of brown discharge after the bleeding stops is normal.

Brown spotting about two weeks after your period lands around ovulation in many cycles, when light spotting can happen as hormone levels shift. If it happens often, note the dates in a tracker and show them to your provider.

Brown discharge instead of a period

Brown discharge but no real period has several possible causes: early pregnancy, hormonal birth control, stress, sudden weight change, heavy exercise, breastfeeding, the start of perimenopause, or conditions like PCOS. Start with a pregnancy test. If it's negative and your period still doesn't come, see a provider if you've missed three periods in a row, or sooner if you're worried.

Brown discharge in early pregnancy

Brown spotting is common in early pregnancy. About 1 in 4 women have some bleeding in the first trimester, most often between weeks 5 and 8, and in one large study it wasn't linked to a higher chance of miscarriage. Still, tell your provider about any bleeding in pregnancy. Get help the same day for heavy bleeding, cramps, pain on one side, shoulder-tip pain, dizziness, or passing tissue.

When to see a provider

See a provider if brown discharge is persistent between periods over several cycles, recurs after sex, smells foul, comes with pelvic pain, or appears after menopause.
