Heavy bleeding after sex with no pain

Friction can cause a small tear that is not painful, while cervical inflammation, dryness, or an infection such as Chlamydia may bleed with little warning. Cervical dysplasia, cervical cancer, and vaginal cancer may also present with bleeding after sex. A symptom cannot establish any of these diagnoses, and many non-cancerous explanations are possible.

Use a pad to monitor the flow and avoid penetrative sex until the bleeding has stopped and you have advice. Contact a clinician promptly for an examination. They may ask about periods, contraception, pregnancy possibility, discharge, medicines, and menopause-related dryness, then consider pregnancy and infection testing or an examination of the cervix. Keep a note of how long the bleeding lasts and whether it returns.

Go to urgent care if the bleeding is heavy or persistent, or if you develop faintness, marked weakness, severe pelvic pain, fever, or pregnancy-related concerns. Do not drive yourself if you feel faint. A repeat episode also warrants a clinical review even when there is no pain.

Ask whether the cervix or vaginal walls look irritated, which tests are appropriate, and whether you need follow-up if the examination is normal. Tell the clinician about the first and most recent episode, flow, sexual activity, contraception, and any discharge.
