Very heavy periods after giving birth: what to know

Periods can take time to return after pregnancy, particularly when breastfeeding. Early cycles may be irregular or heavier as ovulation resumes, but postpartum bleeding and a returned period are different. Bleeding soon after birth, bleeding that becomes heavier after it had eased, or bleeding with fever and pelvic pain may have a different cause.

A heavy period is a common presentation of several womb conditions, including fibroids, adenomyosis, polyps, and an overgrown womb lining. Polycystic ovary syndrome and perimenopause can also disturb cycle timing. Blood loss may lead to iron deficiency anaemia, causing tiredness, headaches, breathlessness, or paleness.

Contact a clinician or maternity service to describe the timing, flow, clots, pain, fever, and whether you are breastfeeding. Mention medicines, contraception, and any pregnancy possibility. Assessment may include checking blood pressure, examining the abdomen or pelvis, and blood tests for anaemia; an ultrasound may be used to examine the womb.

Use the recommended menstrual protection and record how often it needs changing. Avoid self-prescribing hormonal medicines or iron until a clinician has considered breastfeeding, other medicines, and the cause of bleeding.

Get emergency help for rapidly increasing bleeding, faintness, confusion, severe weakness, shortness of breath, chest discomfort, severe abdominal or pelvic pain, fever, or feeling very unwell. These symptoms can accompany major blood loss or infection and should not wait for a routine appointment.

Is this a returned period or postpartum bleeding? Could anaemia be contributing to my symptoms? Do I need an examination, blood tests, or an ultrasound? Which treatments are compatible with breastfeeding and my contraception? What flow or symptoms should trigger urgent help?
