Bleeding During Sex in Perimenopause: What to Know

Falling oestrogen can make vaginal tissue thinner, drier and easier to irritate with friction. However, bleeding may also come from the cervix, an infection, a polyp, a medicine or the uterus, so it should not be assumed to be part of the menopause transition.

Blood noticed during penetration or shortly afterwards is called post-coital bleeding. Vaginal dryness can cause small surface tears, especially if sex also feels sore, burning or tight. Cervical ectropion, cervical or uterine polyps, and sexually transmitted infections are other possible explanations. Less commonly, abnormal cells of the cervix or uterus can cause bleeding and need to be excluded.

Perimenopause often changes the timing and flow of periods, but bleeding linked specifically to sex is different from an irregular period. Note whether the blood appears only after penetration, continues afterwards, or also occurs between periods. Pregnancy remains possible during perimenopause, so a missed period changes how urgently pain and bleeding should be assessed.

Arrange an appointment with a gynaecologist, primary-care doctor or sexual health clinic. Record when the bleeding started, its colour and amount, whether it follows every sexual encounter, and any pain, discharge, odour, itching or urinary symptoms. Bring the names of contraception, hormone treatment, blood-thinning medicines and supplements you use.

Until the cause is clear, pause penetration if it triggers pain or fresh bleeding. A water-based or silicone-based lubricant can reduce friction, while a vaginal moisturiser used regularly may help ongoing dryness. These measures may ease irritation but do not replace an examination. Depending on your history, assessment may include a pregnancy test, infection testing, and examination of the vagina and cervix; further imaging or sampling is guided by the findings.

Book a prompt medical review for any unexplained bleeding during or after sex, particularly when it recurs, becomes heavier, happens between periods, or comes with pelvic pain, unusual discharge, pain during sex or unexplained weight loss. Any vaginal bleeding after menopause needs prompt assessment, even if it happens once and stops.

Seek urgent care if you have missed a period and have unusual bleeding with lower abdominal or pelvic pain, because an ectopic pregnancy must be ruled out. Go to emergency care for heavy bleeding accompanied by fainting, severe dizziness, shortness of breath, chest pain, severe or worsening abdominal pain, or marked weakness.

Ask whether the bleeding appears to come from the vaginal tissue, cervix or uterus; whether pregnancy or infection testing is appropriate; and whether your cervical screening is up to date. If dryness is found, ask which non-hormonal products suit you and whether vaginal oestrogen is appropriate given your medical history. Also ask what change in bleeding should bring you back sooner and when to expect any test results.
