Heavy period after giving birth: what to know

Bleeding after birth is called lochia and gradually changes as the womb heals; it is not the same as a menstrual period. Periods may return at different times, particularly when feeding patterns change. A first period can be heavier or more crampy than expected, but heavy bleeding can also reflect retained pregnancy tissue, infection, a change in the womb, or a bleeding problem. Fibroids, polycystic ovary syndrome, endometrial polyps, adenomyosis, and endometrial hyperplasia are possible causes of heavy periods at other stages of life. Heavy loss can lead to iron deficiency anaemia.

Record whether the bleeding is lochia or a period, its colour and pattern, how quickly protection becomes full, and whether clots, pain, fever, or unpleasant-smelling discharge are present. Contact your maternity or gynaecology team if the flow is heavier than your recent pattern or keeps returning. They may check your blood count, examine you, and arrange imaging. Tell the clinician if pregnancy is possible, if you take medicines that affect clotting, or if you have felt unusually weak.

Get urgent help for sudden heavy flow, repeated soaking of pads, large clots with weakness, faintness, racing heartbeat, breathlessness, severe abdominal pain, fever, or feeling acutely unwell. After birth, these symptoms can signal bleeding or infection and should not wait for a routine appointment.

Ask whether your bleeding fits postpartum recovery or a returning period, whether your womb needs imaging, and whether blood tests show iron deficiency anaemia. Discuss contraception, breastfeeding considerations, and treatment choices if heavy periods continue.
