Bloody Discharge

Bloody discharge is your normal vaginal discharge except it contains blood. Bloody discharge is a sign of bleeding from your cervix, vagina or uterus. The most common time to get it is at the start, during, and at the end of your period. It can look red, pink, or brownish in colour. Bloody discharge can sometimes smell like copper.

What does bloody discharge look like?

Bloody discharge is usually bright red if it contains fresh blood from your period. Bloody discharge can also look pink if there is only a little bit of blood in your discharge. It may appear brown-ish if the blood has been in your vagina for a bit longer.

Is bloody discharge normal?

Discharge can keep your vagina clean and protect it from infections. It is normal to get bloody discharge near your period or in the first 3 months of taking hormonal contraception like the contraceptive pill. If you have other symptoms and bloody discharge out with your period, it may be a sign of pregnancy, an infection, or, more rarely, a gynaecological cancer.

Common causes of bloody discharge

The most common causes of bloody discharge are:

• periods
• pregnancy
• sex
• menopause
• hormonal contraception
• Infection
• gynaecological cancer

Some infections can cause vaginal bleeding and discharge, which causes bloody discharge. STIs are a cause of bloody discharge and can make you bleed after sex or between your period.

Can bloody discharge be a sign of infection?

Bloody discharge might be a sign of infection if you have other symptoms. Other symptoms to look out for include:

• pelvic cramping
• itchiness in and around your vagina
• unusual discharge, such as yellow discharge or smelly discharge
• pain when peeing
• pain when having sex

The most common infections that can cause bloody discharge are:

• STIs like chlamydia which can cause irregular bleeding after sex and between periods
• vaginal infections, such as thrush, which can irritate the vagina and cause bleeding if you have scratched the skin in your vagina whilst itching

If you think you have an infection, you should speak to your doctor.

Periods are the main cause of bloody discharge, as your period blood mixes with your natural discharge. You may get bloody discharge at the start, during, and at the end of your period.

Bloody discharge before period

Bloody discharge may happen at the start of your period because your vaginal wall is beginning to break down. When this happens, blood can become mixed with your discharge, causing bloody discharge. When your period gets heavier, this will be replaced by period blood.

Sometimes, bloody discharge before your period is a sign of pregnancy. If you get bloody discharge and do not start your period when you are supposed to, you should take a pregnancy test and contact your doctor if this is positive.

If you get unexpected bloody discharge before or after your period is due or between periods you should contact your doctor to check for any underlying causes.

Bloody discharge after period

As your vagina uses discharge to clean itself, you may get bloody discharge at the end of your period. This can include blood or dead cells that were left in your vagina at the end of your period. This may be normal for you and if so, you can continue to use a sanitary towel to prevent staining in your underwear.

If you get bloody discharge after your period has ended speak to your doctor. They may suggest further tests to find out why.

Bloody discharge might be a sign that you are pregnant if it happens during the first few weeks of your pregnancy. During the end of your pregnancy, you may get bloody discharge before you go into labour. If you have bloody discharge during your pregnancy, it is best to speak to your doctor or midwife straight away, to check for any serious causes such as an ectopic pregnancy or a miscarriage.

Bloody discharge during pregnancy

During the second and third trimesters, you might get some bloody discharge. This may be more common after sex or after you have been to a midwife appointment. Bloody discharge in pregnancy is caused by a small amount of blood passing through your vagina with your normal discharge.

Bloody discharge during or after sex can be caused by irritation to your vagina during sex or other benign conditions like cervical or endometrial (womb) polyps. However, it’s always important to see your doctor if you have any bleeding during or after sex so they can rule out a more serious cause like an STI or, rarely, gynaecological cancer..

Why do I have bloody discharge after sex?

There are lots of potential causes for bloody discharge after sex. If the skin in your vagina is thinner than usual, such as when you are breastfeeding, sex can cause friction inside your vagina, which may cause light bleeding even if you did not feel anything during sex. It can also be caused by benign conditions like polyps on your cervix or womb or a cervical ectropion (where the lining on the inside of the cervix covers the outside of the cervix too). Even if this only happens once you should contact your doctor so they can rule out any more serious causes.

Another cause of bloody discharge after sex is an STI such as chlamydia. You might also have other symptoms, such as pain when peeing or unusual discharge. You can get tested through our online service or by visiting a sexual health clinic near you. If you think you might have an STI and have pelvic pain, bleeding during or after sex or between periods or pain on having sex these can be signs of a more serious condition called pelvic inflammatory disease and you should contact your GP or local sexual health clinic for treatment.

More rarely bloody discharge during or after sex can be caused by cancer of the vagina, cervix or uterus. It’s really important to attend any smear test appointments you are invited to and to contact your GP urgently if you have any bleeding more than 12 months after your last period (post-menopausal bleeding).

Menopause is the point in your life when your oestrogen levels fall, causing your periods to stop. This does not happen overnight and often, women going through perimenopause can have changes to their periods for a few months or even a few years. If you notice any unexpected bloody discharge during menopause you should contact your GP.

Once your periods have stopped for 12 months, you are in menopause. Bloody discharge after this may be a sign of something more serious. You should get checked if you get a postmenopausal bloody discharge.

Bloody discharge at the start, during or at the end of your period is a sign that your body is working as it should. This means it cannot always be prevented. There are some things you can do to reduce your risk of unexpected bloody discharge, such as:

• getting regularly tested for STIs if you change sexual partners
• using hormonal contraception if your periods are irregular and your doctor feels this is suitable, as this can prevent bloody discharge between periods
• using contraception such as a condom, which reduces your risk of STIs
• attend smear test appointments
• washing your vagina with water and unscented soap, to reduce your risk of vaginal infections like thrush

If the cause of your bloody discharge is something that can be treated, speak to your doctor to find out more about your treatment options.
