How common is bleeding after sex in chlamydia?

Chlamydia can irritate the cervix, the lower part of the uterus, so contact during sex may cause light bleeding. Some people have no other symptoms; others notice unusual discharge, burning when urinating, pelvic discomfort, or bleeding at other times. Bleeding after sex does not identify the cause by itself, and it does not show how long an infection has been present.

Arrange a sexual health assessment if bleeding after sex is new, repeated, or follows sex with a new or untreated partner. Testing may use a urine sample or a vaginal, cervical, or other swab, depending on your symptoms and local practice. Avoid sex until a clinician advises that it is appropriate, and tell recent partners if chlamydia is diagnosed so they can arrange testing and treatment. Do not use leftover antibiotics.

Seek prompt medical care for heavy bleeding, severe or worsening pelvic pain, fever, faintness, vomiting, or feeling very unwell. These features can signal a complication or another condition needing urgent assessment. If you are pregnant or could be pregnant, contact a clinician promptly for bleeding or pelvic pain.

Could chlamydia explain my bleeding, and what other causes should be checked? Which tests do I need? Should my partner or partners be tested? When is it safe to have sex again?
