Menorrhagia after pregnancy: what should you know?

Periods may take time to settle after pregnancy, particularly while feeding patterns and hormones are changing. Heavy bleeding can also be linked with fibroids, adenomyosis, polyps, endometrial changes, polycystic ovary syndrome, perimenopause, thyroid problems, medication effects, or iron deficiency anaemia.

The pattern matters: note how often you change menstrual products, flooding, clots, bleeding between periods, bleeding after sex, pelvic pain, and how long bleeding lasts. Heavy bleeding can lead to iron deficiency, which may cause tiredness, dizziness, headaches, or reduced exercise tolerance.

Keep a bleeding diary and include the date, flow, clots, pain, medicines, breastfeeding status, and any pregnancy possibility. Arrange a clinical review if heavy bleeding continues or affects work, sleep, caring responsibilities, or intimacy.

A clinician may discuss a pregnancy test, blood tests, examination, or imaging according to your history. Do not take leftover medication or iron supplements without advice, especially if you are breastfeeding or taking other medicines.

Seek urgent help for very heavy bleeding with fainting, severe dizziness, weakness, breathlessness, severe pelvic pain, fever, or a possible pregnancy. Sudden heavy bleeding after delivery is an emergency and is different from a later menstrual period.

Book an appointment for repeated heavy periods, bleeding between periods or after sex, persistent pelvic pain, or symptoms of anaemia. Prompt assessment can identify the cause and help protect your energy and wellbeing.

Is my bleeding pattern expected after pregnancy? Could I have anaemia or a uterine condition? Which tests are appropriate? What treatments are compatible with breastfeeding and future pregnancy plans? Which warning signs need urgent help?
