Heavy periods after delivery: what to know

Post-birth bleeding usually changes gradually as the womb heals. When periods return, the first cycles can differ from previous cycles, and breastfeeding can affect timing. Heavy bleeding may instead relate to retained placental tissue, infection, or the womb not contracting properly. Later, conditions such as fibroids, polyps, adenomyosis, or hormone-related cycle changes can also cause heavy periods. Heavy bleeding is a presentation of several possible problems, not proof of one particular condition. Blood loss can lower iron stores and contribute to tiredness, breathlessness, headaches, or reduced concentration.

Use external pads and note how quickly they become soaked, any clots, the colour and smell of the blood, pain, and your temperature. Call your maternity service, midwife, obstetrician, or GP for an individual assessment. A clinician may check your circulation, abdomen, and pelvis, then request a blood count, iron testing, or ultrasound. Tell them about breastfeeding, medicines, contraception, and whether bleeding had been settling before it became heavier. Do not start iron or hormonal treatment without advice about the cause and suitable dose.

Seek emergency help for rapidly increasing bleeding, fainting, severe dizziness, a racing heartbeat, shortness of breath, severe abdominal pain, fever, chills, or feeling unusually weak. An unpleasant-smelling discharge with pain or fever also needs prompt assessment. These symptoms can reflect significant blood loss or infection. If symptoms are milder but the bleeding remains heavy, arrange same-day clinical advice rather than assuming it is a normal first period.

Ask: How can we tell whether this is lochia or a period? Could infection or retained tissue be involved? Do I need an ultrasound or blood tests? What symptoms mean I should return urgently? When can I safely use tampons, menstrual cups, exercise, or a chosen contraceptive?
