Assess delayed abnormal bleeding after birth, distinguish recovery from infection or retained tissue, and organise resuscitation, specialist treatment and recovery follow-up.
Secondary postpartum haemorrhage describes abnormal or heavy vaginal bleeding beginning more than twenty-four hours after birth and within the following twelve weeks. It often presents after the family has returned home. The distinction from normal lochia depends on the amount, trend and associated symptoms: bleeding that becomes heavier again, repeated large clots, offensive discharge or systemic illness deserves assessment. A numerical estimate supplied over the telephone is less reliable than an account of rapid pad saturation, flooding, faintness and change from the preceding days.
Start by determining whether the woman is actively deteriorating. A young previously healthy patient can compensate for blood loss before blood pressure falls. Ask about dizziness on standing, palpitations, breathlessness and reduced urine output, and record serial observations. Existing anaemia may reduce tolerance of further loss. Do not ask a faint woman to drive herself to hospital, and do not delay emergency transfer so that she can locate all her maternity paperwork.
Residual placental fragments can interfere with uterine recovery and maintain bleeding. Infection may develop within retained material, combining an anatomical focus with an inflammatory cause.
Infection of postpartum uterine tissues can disturb healing and produce abnormal lochia. Tenderness, offensive discharge and systemic features help identify this contribution.
Delayed vascular abnormalities, genital trauma or disordered coagulation may underlie persistent haemorrhage. Recurrent episodes with inconclusive initial findings merit renewed specialist evaluation.
Normal postpartum haemostasis depends on uterine contraction and healing at the implantation site. Delayed involution can leave vessels vulnerable to renewed bleeding.
Inflammation disrupts tissue repair and may make the uterine lining friable. Removing an infected retained focus may be necessary for durable improvement.
Blood loss reduces circulating volume and oxygen delivery. Compensation can conceal severity initially, particularly when the patient is young and previously cardiovascularly healthy.
Ask about the onset, repeated gushes, clot size and changes in pad use, alongside symptoms of blood loss. A brief reduction does not guarantee that a recurrent episode is harmless.
Pelvic pain, uterine tenderness and offensive lochia suggest endometritis. Rigors or physiological compromise raise the urgency; fever is not required before considering maternal sepsis.
Tachycardia, pallor, postural symptoms and breathlessness may precede frank hypotension. Interpret observations against baseline and the amount of bleeding still occurring.
Review retained placenta, manual removal, difficult placental separation, caesarean birth, anticoagulation and any bleeding disorder. Establish when the last anticoagulant dose was taken.
Normal discharge generally diminishes during recovery and changes in appearance. A worsening trajectory, systemic symptoms or substantial recurrent clots makes simple reassurance less appropriate.
Menstrual bleeding can resume after birth, especially without breastfeeding. Establishing that explanation requires attention to timing, severity and the absence of concerning associated findings.
A healing tear or surgical wound can bleed independently of the uterine cavity. Direct examination may identify a local lesion requiring different treatment.
Uncontrolled recurrent bleeding can progress to cardiovascular collapse and organ injury. Resuscitation and source control need to proceed together when clinical stability is threatened.
Iron deficiency after blood loss can impair energy, concentration and physical recovery. Symptoms and treatment response require follow-up even when further bleeding has stopped.
Evacuation can cause perforation, additional haemorrhage or intrauterine adhesions. Experienced supervision and a clear indication help balance these risks against leaving the bleeding source untreated.
When the scan reports possible retained products, combine it with clinical findings and the trajectory. The same image may lead to observation in a stable improving patient or intervention in continuing significant bleeding.
Prominent myometrial blood flow or recurrent unexplained haemorrhage should prompt specialist imaging review. Avoid reflex instrumentation until the possibility of a vascular bleeding source has been considered.
Evidence supporting early tranexamic acid around birth should not be converted into an automatic outpatient regimen for bleeding many days later. In major delayed haemorrhage, the senior team applies the relevant haemorrhage protocol and individual assessment.
Explain what is known about the cause and record it for future maternity care. A planned discussion can distinguish a treatable postpartum complication from an assumption that every future birth will follow the same course.
Reassuring a woman because all postpartum bleeding is called lochia can delay recognition of infection or significant recurrent loss.
Automatically equating cavity debris with retained placenta may expose a stable woman to unnecessary instrumentation.
Allowing an apparently normal haemoglobin to override shock or continued bleeding misinterprets the timing of laboratory change.
Focusing entirely on the uterus can miss genital trauma, medication effects or a coagulation disorder contributing to haemorrhage.

A woman presents seven weeks after delivery with new heavy vaginal bleeding and dizziness. A colleague excludes secondary postpartum haemorrhage because six weeks have elapsed. Which interval matches the RCOG definition?
National guidance is shown before implementation-dependent detail. Typical adult dose examples remain subject to patient factors, contraindications and the live BNF or specialist protocol. Source check completed 7 Sept 2026; clinical approval remains outstanding.

Examination and imaging should lead to a management decision rather than a label alone. With consent and a chaperone, assess abdominal tenderness, uterine size and genital wounds. A speculum examination may reveal the bleeding origin or tissue at the cervical opening. Ultrasound can assist, but normal postpartum clot and debris can resemble retained products. Conversely, serious ongoing bleeding cannot be dismissed because an early scan was inconclusive. Communicate the clinical severity to the sonographer and senior obstetrician.
Conservative treatment may be appropriate when bleeding is limited, observations are stable and the proposed diagnosis is supported by assessment. Infection requires antimicrobial treatment, while persistent or substantial bleeding associated with retained tissue may require evacuation. The postpartum uterus is vulnerable to perforation, and instrumentation can lead to adhesions. Explain these risks alongside the risks of continuing haemorrhage or infection, and arrange an experienced operator, suitable anaesthesia and access to blood products when intervention is needed.
Stopping bleeding is only the beginning of recovery. Review haemoglobin in context, treat iron deficiency when indicated and arrange a repeat assessment of symptoms and response. A woman may experience loss of confidence, fear of being alone with the baby or distress when recalling the event. Offer an explanation of the likely cause and treatment in language she can revisit later. Record unresolved investigations and provide a clear route for recurrent bleeding rather than relying on a routine six-week appointment.
The cited SmPC contraindicates severe hypertension, pre-eclampsia, eclampsia, severe cardiac disease, severe hepatic or renal impairment, occlusive vascular disease and sepsis. Use caution with milder hypertension or organ disease. Repeated administration can suppress lactation; persistent bleeding needs reassessment for retained tissue, trauma or coagulopathy before another dose.
Check penicillin allergy, kidney function and previous hepatic reaction. Major bleeding, systemic infection or suspected retained infected tissue requires hospital assessment and possible source control rather than an oral prescription alone.
A fixed haemoglobin trigger is unsuitable for unstable active bleeding. Check identity, temperature, calcium and coagulation during resuscitation, and document the woman's blood product preferences whenever these can be established.
