Why might your period not stop?

Bleeding may continue when ovulation is irregular, because the uterine lining is exposed to changing hormone signals. This can happen during perimenopause, with polycystic ovary syndrome, or with other hormone-related changes. Fibroids, polyps, adenomyosis, infection, and some medicines can also alter bleeding.

Pregnancy-related bleeding, thyroid problems, clotting conditions, and changes in ovarian function need consideration. Menopause means periods have stopped for a full year; bleeding after that point should be assessed rather than assumed to be a new period. The symptom does not identify one cause by itself.

Contact a clinician if bleeding is prolonged, repeatedly heavy, or affecting work, sleep, or usual activities. Record when it began, how often pads or tampons need changing, clots, pain, dizziness, medicines, contraception, and the possibility of pregnancy.

Assessment may include a pregnancy test, blood count, examination, and imaging chosen according to your history. Treatment depends on the cause and may include medicine, treatment of a uterine problem, or support for an underlying hormone condition. Do not stop prescribed medicines without advice.

Seek urgent help if bleeding rapidly soaks through protection, you feel faint or breathless, have severe pelvic pain, fever, confusion, or might be pregnant. Emergency assessment is also needed for weakness or dizziness that makes standing difficult, because ongoing blood loss can cause anaemia or instability.

Ask what may be causing the pattern, whether pregnancy or anaemia needs checking, which examination or scan is appropriate, and how to manage bleeding safely while the cause is investigated. Mention bleeding after menopause or any family history of bleeding problems.
