Key points

Postpartum haemorrhage is heavy bleeding after childbirth, most commonly in the first 24 hours (primary) but sometimes occurring up to 12 weeks later (secondary). It happens when the uterus doesn't contract firmly enough after birth, when there's retained placental tissue, or from tears or other complications.

What is Postpartum Haemorrhage?
Postpartum haemorrhage is heavy bleeding after childbirth, most commonly in the first 24 hours (primary) but sometimes occurring up to 12 weeks later (secondary). It happens when the uterus doesn't contract firmly enough after birth, when there's retained placental tissue, or from tears or other complications.
It is one of the most closely monitored aspects of care immediately after birth, and hospital staff are trained to recognise and treat it quickly. Most cases are managed effectively with prompt treatment, including medication to help the uterus contract, and occasionally further procedures.
02 · Understand
Clinical context
Hospital staff monitor closely after birth
Bleeding and uterine tone are checked regularly in the hours after birth specifically to catch postpartum haemorrhage early, when it responds best to treatment.
03 · Act
After You've Gone Home
- 1Bleeding that suddenly becomes heavier than your normal post-birth bleeding
- 2Passing large clots, especially with dizziness or a racing heart
- 3A fever alongside heavier bleeding, which could suggest infection
- 4Any bleeding that concerns you, however many weeks after birth

Practical steps
This Requires Immediate Medical Treatment
Heavy bleeding after birth is a medical emergency, whether it happens in hospital or after you've gone home — seek help immediately rather than waiting to see if it settles.
- 1Seek emergency help for heavy bleeding at home.Call emergency services or go to your maternity unit immediately — don't wait or try to manage it yourself.
- 2Know what's normal versus concerning.Post-birth bleeding gradually lightens over several weeks — a sudden increase, especially with clots, is not normal.
- 3Rest and accept help after birth.Reducing physical strain in the weeks after birth supports overall recovery.
- 4Attend your postnatal check.This is an opportunity to raise any concerns about ongoing bleeding or recovery.
