Bleeding after 12 months without a period

After twelve months without menstruation, bleeding may come from thinning vaginal or uterine tissue, a polyp, infection, or hormone treatment. Less commonly, changes in the womb lining need investigation. Menopause is a common context for this pattern, but bleeding itself does not identify its cause.

A clinician may ask about the colour, amount, timing, medicines, hormone therapy, and pain. They may examine you and arrange tests such as an ultrasound or a sample of the womb lining. Do not wait for a second episode before seeking advice.

Book an appointment with a doctor or gynaecology service, even if the bleeding stopped. Write down when it began, how long it lasted, whether it followed sex, and any discharge or pelvic discomfort. Bring a list of medicines, hormone treatments, and supplements.

Periods Stopped provides context for absent menstruation, while conditions such as Polycystic Ovary Syndrome, Premature Ovarian Insufficiency, or Turner Syndrome may be relevant only when supported by your age, history, and examination.

Use urgent services for bleeding that is heavy or worsening, severe abdominal or pelvic pain, fainting, breathlessness, or pronounced weakness. Fever or foul-smelling discharge also needs prompt review because infection may require treatment.

Ask which examination or scan you need, whether your medicines could contribute, whether the womb lining needs sampling, and how quickly you should receive follow-up for the result.
