Bleeding After Sex: Common Causes and When to Get It Checked

Noticing bleeding after sex can be unsettling, and many women feel embarrassed to mention it. However, bleeding after sex is something gynaecologists see often, and in most cases the cause is harmless and easy to treat. Even so, it should always be checked, because occasionally it can be an early sign of something that needs attention.

What is bleeding after sex?

Doctors call it postcoital bleeding. It can range from a few spots of blood to heavier bleeding, and it may happen once or keep returning. Some women also notice pain during or after intercourse. You can find a fuller overview on our postcoital bleeding page.

Common causes of bleeding after sex

Most causes are benign, which means they are not cancer. The most common include:

• Cervical ectropion: delicate cells from inside the cervix sit on its outer surface, where they bleed easily. It is common in younger women, in pregnancy and in those taking the contraceptive pill.
• Cervical or womb polyps: small, usually harmless growths that can bleed when touched.
• Infections: sexually transmitted infections such as chlamydia can inflame the cervix and cause bleeding.
• Vaginal dryness: particularly after the menopause, when thinner tissues are more easily irritated.
• Friction or minor injury: which usually settles quickly by itself.

Less commonly, bleeding after sex can be a sign of abnormal cells on the cervix, or of cervical cancer. This is why we never simply assume the cause is harmless without checking. A proper examination gives you a clear answer.

When to get it checked

You should see your GP or a gynaecologist if you have bleeding after sex, even if it has only happened once. It is especially important to seek advice if it keeps happening, if you are over 40, if you have gone through the menopause, or if you have other symptoms such as unusual discharge, pain or bleeding between periods.

Please do not wait for your next routine screening appointment. A smear test is designed for people without symptoms rather than as a way to investigate bleeding. New symptoms always deserve their own assessment.

What your gynaecologist will look for

Your appointment will start with a conversation about your symptoms, your periods, your contraception and your sexual health. Your gynaecologist will then examine you, usually including a gentle speculum examination so that the cervix can be seen clearly. Swabs may be taken to test for infection.

Depending on what is found, you may be offered further tests. These can include a pelvic ultrasound scan, or a colposcopy, which uses a magnifying instrument to look closely at the cervix and take a small sample if needed. Cancer Research UK has clear information on cervical cancer and its symptoms if you would like to read more.

Treating bleeding after sex

Treatment for bleeding after sex depends entirely on the cause. Infections are treated with antibiotics, and your partner may need treatment too. Polyps can usually be removed quickly and simply, often during an outpatient appointment. Vaginal dryness after the menopause often responds well to lubricants, moisturisers or local oestrogen.

A cervical ectropion often needs no treatment at all. If it causes troublesome bleeding, however, it can be treated with a simple procedure. If abnormal cells are found, they can usually be treated successfully long before they have a chance to develop into cancer.

Do not let embarrassment stop you

Talking about bleeding after sex can feel awkward, but gynaecologists discuss intimate symptoms every day, and our aim is always to put you at ease. The Royal College of Obstetricians and Gynaecologists offers helpful patient information if you would like to prepare for your appointment. Writing down your symptoms beforehand can also help.

Getting checked brings reassurance, and if treatment is needed, starting early makes it simpler and more effective. If you have noticed bleeding after sex and would like to see a specialist, please contact our team to book a consultation with Mr Abu.
