Classify the bleeding by anatomical source and by its relation to pregnancy, childbirth and menstruation; treatment must address that source. The amount of visible genital haemorrhage does not measure all the loss: a ruptured ectopic pregnancy or concealed placental abruption can cause major internal blood loss. Initial assessment of severe bleeding concerns the circulation, anaemia and the need for resuscitation while the cause is established. Bleeding from the urethra or rectum must first be distinguished from genital bleeding.

Local sources outside the uterine cavity. The vulva and vagina may bleed from lacerations after childbirth or other trauma, an inflamed lesion, a foreign body, a vascular lesion or cancer. Examination localizes the loss; treatment is local compression and repair of a significant laceration, removal of the foreign body, cause-directed treatment of infection, or specialist management of the lesion. A cervical polyp, cervical ectropion, cervicitis or cervical cancer can cause bleeding from the cervix, often noticed between periods or after intercourse. A suitable polyp can be removed and examined; inflammation requires its cause to be established, while a suspicious lesion requires diagnostic assessment rather than indiscriminate cauterization. After menopause, thin, fragile vulvovaginal tissues can also bleed; this does not remove the need to investigate a suspicious lesion. These are different conditions, not one disease called “uterine haemorrhage”. ^[ref]

Bleeding from the endometrium. Heavy or irregular menstruation may accompany ovulatory dysfunction, uterine fibroids, endometrial polyps, adenomyosis, a coagulopathy, medication effects or endometrial cancer. Modern assessment includes the menstrual and drug history, a full blood count, and selected ultrasound, hysteroscopy or tissue sampling according to the suspected cause. Where appropriate, menstrual bleeding can be reduced with tranexamic acid or hormonal treatment; an intracavitary polyp or uterine fibroid may instead need targeted removal. Persistent postmenopausal bleeding must not simply be treated as an ordinary period. ^[ref]

Early pregnancy. A miscarriage may bleed while pregnancy tissue separates or remains in the uterus. In a stable, confirmed case, expectant, medical or surgical management may be appropriate; heavy continuing loss or infection changes the urgency. Ectopic pregnancy requires a separate plan: selected stable cases may be monitored or treated medically, but rupture with haemorrhagic collapse requires urgent operative control, not treatment of the vagina as though it were the principal source. A hydatidiform mole is another pregnancy-related source of abnormal bleeding; current management includes removal by suction evacuation and subsequent human chorionic gonadotropin surveillance for persistent disease. ^{[ref] [ref] [ref]}

Later pregnancy and labour. Placenta praevia commonly produces relatively painless bleeding, whereas placental abruption more often causes pain and uterine tenderness; these are useful patterns, not infallible rules. Management depends on the mother's circulation, the fetus, the placental lesion and the stage of pregnancy, with urgent delivery when required. A blind digital cervical examination is inappropriate before a possible placenta praevia has been excluded. Ruptured vasa praevia causes fetal rather than maternal bleeding and demands a different interpretation. A small blood-stained mucous “show” during cervical change is not equivalent to these pathological losses. ^{[ref] [ref]}

After delivery. The principal categories are failure of uterine contraction, retained placental tissue, trauma and disordered coagulation. For uterine atony, the aim is to restore contraction with uterine massage and an appropriate uterotonic. Retained tissue, a genital laceration or uterine inversion requires correction of that particular cause; a coagulopathy requires haemostatic support. With placenta accreta spectrum, attempted forcible separation can provoke severe haemorrhage. Current care combines resuscitation with cause-directed measures, and can require tranexamic acid, balloon tamponade, embolisation or surgery when initial measures fail. Later postpartum bleeding also raises retained tissue and endometritis. ^[ref]

The 1865 distinction. An answer of the period could distinguish menstrual loss, local lesions, pregnancy-related haemorrhage and post-delivery failure of contraction through the history and physical examination. Compression, local plugging, removal of an accessible lesion and obstetric intervention were among the available approaches; their use was debated. The 1864 discussion of placenta praevia documents such disagreement. Modern imaging, blood banking, the present drug regimens and current operative pathways must not be attributed to that practice. Nor should historical astringents or depletion be substituted for identifying the source. ^[ref]

Separate evidence produced by the mother from evidence identifying the fetus. The classical presumptive, probable and positive grouping expresses increasing diagnostic confidence; it is not a numerical probability scale.

Presumptive signs include missed menstruation, nausea or pregnancy-associated vomiting, breast enlargement and tenderness, changes in the areola, urinary frequency and the mother's sensation of fetal movement, traditionally called quickening. Each can have another explanation. Amenorrhoea may result from illness or endocrine disturbance; abdominal enlargement can arise from a pelvic mass, ascites or other causes. A report of movement is not equivalent to movement detected independently by the examiner.

Probable physical signs include a progressively enlarged uterus with the appropriate change in contour, softening of the cervix and uterine tissues, increased vascularity and colour change of the genital mucosa, and intermittent uterine contractions. Ballottement is the rebound of a movable object within fluid when it is displaced: in the right clinical setting it supports a gravid uterus, but the physical phenomenon alone does not identify a living fetus. A vascular sound heard over the uterus follows the maternal circulation and is not the fetal heartbeat.

Positive evidence available to the 1865 examiner was a fetal heartbeat heard with a stethoscope, unmistakable fetal movements appreciated during examination, and identification of fetal parts. Repeated examination as pregnancy advances strengthens their interpretation. The examiner should compare the perceived heartbeat with the maternal pulse rather than accept any abdominal sound as fetal. These findings generally become useful later than the earliest symptoms, so their absence early on does not exclude pregnancy. The mother’s quickening remains a symptom; independently established fetal movement is a different kind of evidence.

Modern additions. Human chorionic gonadotropin testing can detect pregnancy-related tissue before the classical physical signs become conclusive. A positive test does not establish location or continuing viability: it can occur in ectopic pregnancy and must be interpreted in context. Ultrasound can establish location and show an embryo or fetus with cardiac activity. Very early uncertain findings may require repeat assessment rather than a premature conclusion. These technologies are later developments, not signs that an 1865 candidate could have obtained. ^{[ref] [ref]}

Suspect uterine retroversion from examination and the clinical setting, while distinguishing an incidental position from symptomatic disease or an incarcerated pregnant uterus. Pelvic pressure, backache, painful menstruation, pain with intercourse, difficulty voiding or rectal pressure can prompt assessment, but none proves that the uterine position is the cause.

In retroversion the uterus tilts backwards as a whole; uterine retroflexion instead describes bending between its body and cervix. The two can coexist. On an appropriate pelvic examination, the uterine body may be felt posteriorly while the cervix points more anteriorly. Mobility, tenderness, a pelvic mass and the possibility of pregnancy affect interpretation. Symptoms may come from associated endometriosis, adhesions or another pelvic disorder rather than the tilt itself.^[ref]

The especially important historical presentation is early or mid-pregnancy with increasing pelvic pressure and urinary retention. An enlarged backward-lying uterus can remain trapped beneath the pelvic brim, distorting the cervix and bladder outlet. Dribbling urine can represent overflow from retention, not adequate emptying. A distended urinary bladder and a posterior pelvic mass require careful assessment rather than treatment with a diuretic. A pre-1866 account of retroversion after conception emphasized retention as a principal presenting problem.^[ref]

Historical treatment aimed first to empty an overdistended urinary bladder with a catheter, then to restore position where appropriate and prevent recurrence, sometimes with positional measures or a vaginal pessary. A fixed, painful or possibly pregnant mass made blind forceful manipulation particularly hazardous. Describing the aim of a period manoeuvre does not make repeated unassessed attempts at repositioning acceptable.

Modern correction: an asymptomatic retroverted uterus commonly needs no treatment. Symptoms call for investigation of their actual cause; retroversion alone does not establish infertility or explain every miscarriage. For selected symptomatic mobile cases, conservative support or a fitted vaginal pessary may be considered, while associated disease is managed on its merits.^[ref] Suspected incarceration in pregnancy, especially with urinary retention, needs urgent obstetric assessment. Ultrasonography can clarify the anatomy; magnetic resonance imaging may help when the relation of the uterus, urinary bladder and cervix remains uncertain. Drainage of the urinary bladder and any attempt at reduction are specialist decisions guided by gestation, anatomy and complications. Published evidence is largely case reports and series, so a single successful method is not a universal rule.^[ref]

The source's “last half” includes a wider interval than the definition of antepartum haemorrhage from 24 weeks used by the cited British guideline. No diagnosis follows from intermittency alone.

In placenta praevia, the placenta covers the internal opening of the cervix. Development of the lower uterine segment and opening of the cervix disturb attachment at the placental margin, exposing maternal vessels. Bleeding is often painless and recurrent and can become severe after apparently minor episodes. In placental abruption, a normally situated placenta separates prematurely. Bleeding into the placental bed reduces exchange with the fetus; pain, tenderness and increased tone of the uterus are suggestive, but their absence does not exclude it. Some blood can remain concealed, making visible vaginal loss a poor measure of total loss.

In vasa praevia, vulnerable fetal vessels run through the membranes near the internal cervical opening. Rupture, particularly when the membranes break, can cause rapid fetal blood loss while the mother remains comparatively stable. Other causes include a blood-stained cervical “show” in labour, cervical ectropion, a cervical polyp, local infection, trauma, and occasionally a tumour of the cervix or vagina. These must be distinguished from placental bleeding rather than presumed harmless from a small volume alone.^[ref]

For an 1867 answer, the classic contrast is between “unavoidable” haemorrhage from placenta praevia and “accidental” haemorrhage from premature separation of a normally implanted placenta. The adjectives are historical classifications, not claims that either outcome is inevitable or that every placental abruption follows an accident. Period management sought to conserve maternal strength when slight bleeding settled, then accomplish delivery when recurrent loss or labour made waiting dangerous. For partial placenta praevia, rupture of membranes was used in suitable labour to bring the presenting part down against the bleeding region. For more extensive placenta praevia, vaginal plugging, dilation and turning to deliver the child were debated and used. Contemporary discussion shows disagreement about how long it was safe to temporise: an 1864 report describes both advocates of early delivery and arguments about plugs, dilating bags and turning.^[ref]

Those measures belong to the history of managing haemorrhage before modern operative safety, imaging and transfusion services. They must not be carried over as a modern algorithm: a vaginal plug can conceal continuing loss; attempted separation of the placenta or turning through placenta praevia can aggravate bleeding and endanger the fetus.

In current practice, the initial response to significant bleeding is hospital assessment with maternal resuscitation, monitoring, intravenous access and blood tests, with blood products available according to severity. Determine placental position by ultrasonography, assess the fetus according to gestational age, and look for local causes with appropriate examination. Do not perform a digital vaginal examination while placenta praevia remains a possible explanation until it has been excluded by ultrasonography. A carefully performed speculum examination and a skilled transvaginal ultrasound are different procedures; the latter is a safe, useful way to locate the placental edge. A normal ultrasound does not exclude placental abruption.^[ref]

During the later preterm months, a stable mother and fetus after bleeding has stopped may be managed expectantly under specialist supervision. The plan includes surveillance, correction of anaemia, readiness to return urgently, and individual decisions about admission and timing of birth. Corticosteroids are considered when preterm delivery is likely; they do not treat the bleeding. Ongoing major haemorrhage, maternal instability or serious fetal compromise can require delivery regardless of immaturity. This is not a policy of waiting for full term at any cost.

At or near term, the cause determines the route. Persistent placenta praevia covering the internal cervical opening requires caesarean birth; repeated bleeding may require earlier delivery. Current 2026 guidance individualises timing for uncomplicated low-lying placenta or placenta praevia and advises considering planned birth no later than 37 weeks and 6 days. A low-lying placental edge that does not cover the opening requires individual assessment of whether vaginal birth is appropriate. These timings are present guidance, not an 1867 rule.^[ref]

With placental abruption, expedite delivery when indicated by maternal or fetal condition; caesarean birth is often required for a live compromised fetus when vaginal delivery is not imminent, while vaginal delivery may be appropriate in other circumstances. A local cervical lesion requires cause-specific management. Suspected rupture of vasa praevia is an emergency for urgent caesarean birth and neonatal resuscitation; an antenatally detected vasa praevia calls for planned birth before labour or membrane rupture.^[ref] The central distinction is therefore safe observation of a settled, stable preterm episode versus timely delivery for an ongoing hazard, not a single remedy for every late-pregnancy bleed.

After the fetus is born, contraction and retraction of the myometrium reduce the area of the placental bed. The placenta cannot shrink with it and normally separates through the maternal decidua. Continued contraction compresses the maternal vessels crossing the myometrium, providing an important mechanism of haemostasis. A fragment left attached can both expose bleeding vessels and interfere with effective contraction.

Three mechanisms organise the causes:

Consequences include immediate or delayed postpartum haemorrhage, hypovolaemic shock, anaemia, endometritis and sepsis. Retained fragments may delay normal shrinking of the uterus. Forceful pulling on the umbilical cord adds the risks of cord rupture and uterine inversion. Conversely, indiscriminate delay while bleeding continues can be fatal.

An 1867 answer would assess bleeding, the size and contraction of the uterus, whether separation had occurred and whether the outlet was obstructed. Emptying the urinary bladder, encouraging effective contraction and supporting the uterus were rational preliminary principles. If the placenta remained attached or trapped and the circumstances demanded intervention, manual removal with external support of the uterus was the principal operative resource. The historical difficulty was to distinguish a removable attachment from a dangerously adherent one. A September 1867 report describes an apparent “hour-glass” retention actually relieved by loosening a tight abdominal binder; it is useful evidence for examining the mechanism rather than trusting the diagnostic label.^[ref] The case is an observation, not proof that all retention has an external cause.

Current care monitors blood loss and maternal condition, secures intravenous access and obtains skilled obstetric help. With active third-stage management, failure to complete the third stage of labour by 30 minutes is prolonged; with physiological management, the cited NICE threshold is 60 minutes. These thresholds do not justify waiting through active haemorrhage or instability. A trained clinician may use controlled cord traction with uterine counterpressure under appropriate conditions; unopposed pulling is not the same technique.^[ref]

When removal is required, examination and manual removal take place with appropriate anaesthesia, aseptic technique, external support and readiness to manage haemorrhage. The placenta and membranes are checked for completeness; persistent bleeding prompts assessment for retained fragments, uterine atony, trauma and disordered clotting. Antibiotic prophylaxis accompanies manual removal. Give uterotonics for associated postpartum haemorrhage and to maintain contraction after removal, rather than repeatedly giving them as a substitute for removing a retained organ in a non-bleeding patient. WHO's 2025 recommendations advise preparing for manual removal after 30 minutes if the placenta remains undelivered and distinguish this decision from treatment of established postpartum haemorrhage.^[ref]

If no safe separation plane exists and placenta accreta spectrum is suspected, repeated forceful attempts to peel off the placenta can precipitate catastrophic haemorrhage. Escalate to an experienced multidisciplinary team and a haemorrhage plan. Definitive surgery, including hysterectomy, may be necessary; selected conservative management leaving the placenta in place requires specialist selection and follow-up. Current guidance explicitly advises avoiding attempted separation in women with a high probability of placenta accreta spectrum.^[ref] Thus the word “retained” identifies an urgent clinical problem, but the cause determines whether ordinary manual separation is safe.
