Heavy period every 2 weeks: what it can mean

Two episodes of bleeding close together may reflect bleeding between periods rather than two complete menstrual cycles. Hormonal shifts can alter ovulation and the uterine lining. Other possible contributors include uterine fibroids, adenomyosis, endometrial polyps, endometrial hyperplasia, perimenopause, or polycystic ovary syndrome. A clinician may also consider pregnancy-related bleeding, medication effects, or a bleeding disorder.

The pattern matters: record the first and last day, how often you change pads or tampons, clots, pelvic pain, and bleeding after sex. Tiredness, breathlessness, headaches, or a racing heartbeat can occur when repeated blood loss contributes to iron deficiency anaemia.

Arrange a medical appointment rather than treating repeated episodes as separate periods. A clinician may review pregnancy possibility, medicines, contraception, and your cycle history, then decide whether examination, blood tests, or an ultrasound is appropriate. Use a symptom diary and mention any family history of fibroids or bleeding problems.

Seek urgent care if bleeding rapidly soaks through protection, you feel faint or unusually weak, or you have severe pelvic pain, fever, or shortness of breath. Emergency assessment is also appropriate when heavy bleeding occurs during a possible pregnancy.

Ask what counts as a cycle in your pattern, whether you need testing for anaemia or pregnancy, and which treatment options fit your health, contraception needs, and plans for pregnancy.
