Light bleeding after rough intercourse: what to know

A small amount of spotting may follow irritation of the vagina or cervix, hormonal shifts, or changes in the menstrual cycle. Chlamydia can present with bleeding after sex or between periods, sometimes alongside unusual discharge, pelvic discomfort or pain when urinating. Genitourinary Syndrome of Menopause can make vaginal tissues thinner and easier to irritate. Bleeding after sex does not by itself identify a serious condition. Cervical dysplasia and cervical cancer can present with bleeding after sex, while vaginal cancer can also cause unusual bleeding. These conditions require clinical assessment rather than self-diagnosis.

Record when the bleeding happened, its colour and amount, whether it followed penetration or another trigger, and whether it stopped. Note pain, discharge, fever, urinary symptoms and your period dates. Take a pregnancy test if pregnancy is possible. Arrange a routine appointment if bleeding recurs, continues, happens after sex, or is new after menopause. A clinician may ask about contraception, medicines and sexual health and may examine the vagina and cervix. If cervical changes need further evaluation, a cone biopsy is one procedure that may be discussed.

Seek urgent medical care for heavy bleeding, severe or one-sided pelvic pain, fainting, marked dizziness, fever, or bleeding during a possible pregnancy. Seek prompt assessment for recurring bleeding, bleeding after menopause, or bleeding with foul-smelling discharge or significant pain. Do not wait for a routine visit if you feel weak or unwell.

Could irritation, contraception, infection or pregnancy explain this bleeding? Do I need an examination or testing for Chlamydia? When should I have cervical screening? Which changes mean I should return sooner?
