Ovulation spotting after intercourse: what to know

Around ovulation, changing hormone levels can make the lining of the uterus shed a small amount of blood. Friction during intercourse may also irritate the cervix or vaginal tissue, especially when there is dryness. The blood may appear pink, red, or brown and may be noticed on toilet paper or underwear.

Bleeding after sex is a symptom, not a diagnosis. Cervical infections such as Chlamydia, cervical dysplasia, polyps, fibroids, and less commonly cervical or womb cancer can also present with bleeding between periods or after intercourse. A pattern that is new, recurrent, heavier, or unrelated to your cycle should be checked.

Note when the spotting occurred, how long it lasted, its colour, and whether sex was painful. Record where you were in your cycle and any discharge, pelvic pain, fever, or chance of pregnancy. Use a lubricant if dryness may have contributed, and avoid inserting anything into the vagina while bleeding is unexplained or worsening.

Arrange a clinician visit if the episode returns, happens after most instances of intercourse, or comes with unusual discharge or pelvic discomfort. Assessment may include a pregnancy test, an examination of the vagina and cervix, infection testing, and screening according to your history.

Seek urgent medical help for heavy bleeding, severe or one-sided pelvic pain, fainting, marked dizziness, fever, or a positive pregnancy test with bleeding or pain. These features can signal a problem that needs prompt examination. If bleeding continues, becomes more frequent, or occurs after menopause, arrange medical review even when there is no pain.

Ask whether the bleeding pattern suggests cervical irritation, an infection, or another cause; whether you need an examination or tests; and which changes should prompt urgent care. Bring your cycle notes and a list of medicines, contraception, and recent screening results.
