Resuscitate first and find the cause
Collapse, haemodynamic change, uncontrolled bleeding, sepsis, peritonism or severe unilateral pain after abortion may represent haemorrhage, uterine injury, ectopic pregnancy or invasive infection.
Action: Use ABCDE care, obtain large-bore access, full blood count, lactate, group and crossmatch, give broad-spectrum intravenous antibiotics promptly when sepsis is suspected, and involve senior gynaecology and anaesthesia for urgent imaging and source control.
Purpose and principles
Differentiate expected recovery from haemorrhage, infection, ongoing pregnancy, ectopic pregnancy and procedural injury, then provide proportionate physical and emotional aftercare.
Good aftercare begins before treatment. Explain the likely timing and amount of pain and bleeding, whether products of pregnancy may be seen, common medicine effects, the planned completion check and how to reach help at any hour. Ask where messages can safely be sent and whether home circumstances permit privacy, analgesia, sanitary protection and transport. A patient who knows what is expected can identify deviation early without being frightened by normal cramping or dismissed when a serious symptom emerges.
After medical abortion, pain and bleeding usually intensify after misoprostol and ease after the pregnancy passes. Clots, visible tissue and temporary nausea, vomiting, diarrhoea, chills or feverishness can occur. Bleeding may continue more lightly for days or intermittently for longer. After vacuum aspiration or dilatation and evacuation, cramping and spotting are common, but some patients have little bleeding. Symptom trajectory matters: recovery should generally improve, whereas increasing pain, recurrent heavy loss or systemic illness needs reassessment.
Indications, selection and cautions
Expected medical recovery
Cramping and heavier bleeding peak around expulsion then improve, with transient gastrointestinal or chill symptoms and a later negative completion test.
Haemorrhage pattern
Rapid ongoing loss with large clots, dizziness, tachycardia, hypotension or anaemia requires urgent cause-directed haemostatic care.
Infection pattern
Persistent fever, rigors, offensive discharge, uterine tenderness and worsening systemic observations point toward endometritis or septic retained tissue.
Ongoing pregnancy pattern
Minimal response to misoprostol, continuing pregnancy symptoms or a positive service-provided test indicates need for ultrasound and treatment review.
Perforation pattern
Severe disproportionate abdominal pain, peritonism, distension, shoulder pain or collapse after instrumentation suggests uterine and possible visceral injury.
Red flags requiring action
Bleeding that is rapidly soaking protection, passing very large clots, causing dizziness, syncope, breathlessness or weakness requires urgent assessment rather than remote reassurance.
Fever, rigors, offensive discharge, worsening pelvic pain, tachycardia or systemic illness can indicate endometritis, retained infected tissue or sepsis.
Persistent pregnancy symptoms, very little bleeding after medical treatment or a positive scheduled follow-up test raises concern for ongoing pregnancy or failed treatment.
Assessment before treatment
01Full blood count and coagulationFirst step
Why
Assess anaemia, infection response, platelet count and coagulopathy during significant bleeding or systemic illness.
Interpretation and limitations
Acute haemoglobin can initially appear preserved; physiology, serial change and active loss determine transfusion and operative urgency.
02Group, screen and crossmatch
Why
Prepare compatible blood and identify transfusion needs in suspected major post-abortion haemorrhage.
Interpretation and limitations
Do not wait for every result before emergency source control; activate the major-haemorrhage pathway when clinical criteria are met.
Endometrial thickness alone does not diagnose clinically important retained products; combine vascularity and contents with symptoms, bleeding and infection.
04Quantitative hCG and pregnancy test
Why
Evaluate continuing pregnancy, ectopic pregnancy or unexpected persistence after the scheduled completion check.
Interpretation and limitations
A positive low-sensitivity test or abnormal hCG trajectory needs clinical and imaging review; bleeding does not prove an intrauterine pregnancy ended.
Treatment approach
01DischargeMake expected recovery and escalation explicitFirst stepEscalationTreatment is complete and the patient is clinically suitable to leave the service.+
1Explain method-specific pain, bleeding, gastrointestinal effects and the likely recovery trajectory in an accessible written and verbal format.
2Provide a functioning 24-hour number and urgent instructions for collapse, very heavy loss, increasing pain, fever, offensive discharge or persistent pregnancy symptoms.
3Supply any completion test, analgesia plan and chosen contraception, confirm safe contact preferences and offer emotional or bereavement support without compulsion.
02Heavy bleedingResuscitate and control the anatomical causeBleeding is ongoing, physiologically significant or accompanied by collapse and severe symptoms.+
1Activate ABCDE and major-haemorrhage care as indicated, obtain large-bore access, bloods and crossmatch and call senior gynaecology and anaesthesia.
Complications, monitoring and follow-up
Recheck observations, bleeding, pain and uterine or abdominal findings after every intervention for haemorrhage or infection until a sustained response is clear.
Track the service-provided completion test and ensure a positive or missed result reaches a clinician who can exclude ongoing or ectopic pregnancy.
Review cultures, pathology and operative findings after admission, narrowing antimicrobial treatment and arranging further imaging when recovery does not follow expectation.
Document blood products, suspected perforation and any visceral injury clearly for future pregnancy and surgical care, including follow-up with the responsible specialty.
Offer contraception review, counselling or mental-health support according to individual need, and assess suicidal thoughts or safeguarding danger through urgent established pathways.
Special situations
Bleeding does not confirm location
A decidual reaction can pass while a tubal ectopic persists, so new unilateral pain after early treatment remains a diagnostic emergency.
Misoprostol can mimic fever
Transient chills and temperature elevation may be pharmacological, but persistence, worsening pain and systemic deterioration point toward infection.
Thickness is not retained tissue
A thick heterogeneous endometrium is common after abortion; symptoms, vascular material and clinical trajectory determine whether intervention is useful.
Aftercare protects confidentiality
Phone calls, portal messages, medicine packaging and transport can expose abortion or abuse, so safe communication is part of discharge planning.
Support should follow preference
Routine compulsory counselling can pathologise normal responses, while rapid access to chosen emotional or bereavement support remains essential.
Common pitfalls
01
Calling all post-medical fever a misoprostol effect despite persistence or systemic deterioration.
02
Reassuring from vaginal bleeding when the initial pregnancy location was never established.
03
Using endometrial thickness alone to diagnose retained products and arranging unnecessary curettage.
04
Observing severe post-procedure pain with escalating opioids instead of excluding perforation and visceral injury.
05
Failing to trace a positive or unreturned completion test after home medical care.
06
Imposing emotional counselling or contraception instead of offering care based on the patient's preferences.

Sources
Sources and review status
National guidance is shown before implementation-dependent detail. Apply principles in context and verify current guidance when a decision affects care. Source check completed 27 Aug 2026; clinical approval remains outstanding.
Haemorrhage can arise from uterine atony, retained tissue, cervical laceration, perforation, abnormal placentation or coagulopathy. Assess physiology and estimated ongoing loss, establish venous access, obtain blood count, coagulation, group and crossmatch and call senior support. Pelvic examination and ultrasound can locate retained material or free fluid in a stable patient, but should not delay theatre in shock. Management may include uterine massage, uterotonic medication, repeat aspiration, balloon tamponade, repair, uterine-artery embolisation or surgery according to cause and response.
Post-abortion infection ranges from local endometritis to rapidly progressive sepsis. Fever that persists beyond a transient misoprostol effect, offensive discharge, uterine or pelvic tenderness and deteriorating observations support infection. Take cultures and lactate where this does not postpone treatment, administer broad-spectrum intravenous antibiotics using the current obstetric-gynaecology sepsis protocol and obtain source control. Retained infected pregnancy tissue generally requires uterine evacuation once resuscitation and operative planning are underway. Consider sexually transmitted infection and rare toxin-mediated disease.
Ongoing pregnancy follows failed medical treatment or incomplete procedural completion and is more likely when there was no expected bleeding or pregnancy symptoms continue. Use the planned low-sensitivity test after early home care and assess a positive result with ultrasound and quantitative hCG as needed. Discuss repeat medical treatment or aspiration promptly. If the patient considers continuing after misoprostol exposure, explain that a recognised anomaly spectrum includes Möbius-type cranial-nerve palsies, limb and central-nervous-system defects, orofacial clefts, arthrogryposis and talipes, while the absolute risk is not quantified; arrange fetal-medicine or UKTIS counselling and targeted ultrasound of viability, growth and development. Retained products without ongoing gestation may be managed expectantly, medically or surgically according to bleeding, infection and preference.
Ectopic pregnancy remains possible if treatment occurred before a definite intrauterine pregnancy was seen. Abortion medicines do not treat a tubal ectopic. Unilateral pain, shoulder-tip pain, collapse or persistent hCG requires urgent early-pregnancy assessment even if vaginal bleeding occurred. Uterine perforation is primarily a surgical complication and can coexist with bowel, bladder or vascular injury. Disproportionate pain, peritonism, distension or instability after instrumentation warrants urgent imaging or laparoscopy rather than repeated opioid medication and observation alone.
Most people recover without complication and do not need routine face-to-face review. Provide self-assessment or remote follow-up after early home medical abortion and a clear return pathway. Menstruation and fertility can return quickly, so offer contraception according to preference but never make acceptance a condition of care. Advise on sexual activity, bathing, tampons or exercise through evidence-based service guidance rather than unsupported restrictions; individual comfort and infection symptoms guide recovery.
Emotional responses range from relief to sadness, grief, uncertainty or a mixture, and may differ when abortion followed fetal diagnosis or coercive circumstances. Ask what support is wanted, preserve confidentiality and offer counselling, bereavement or mental-health care without implying pathology. NICE advises reassurance that abortion is not associated with increased infertility, breast cancer or mental-health problems. Persistent distress, suicidal thinking, trauma symptoms or unsafe home circumstances still merit ordinary urgent mental-health and safeguarding pathways.
Key points
Expected recovery depends on method and gestation: cramping and bleeding are usually heavier during medical expulsion, while surgical abortion often gives shorter, lighter bleeding and procedure-related discomfort.
Transient nausea, diarrhoea, chills and feverishness can follow misoprostol, but persistent fever, worsening pain or systemic illness should not be attributed to the medicine.
Major post-abortion differentials are haemorrhage, retained products, ongoing pregnancy, infection, ectopic pregnancy, cervical trauma and uterine perforation with possible visceral injury.
Resuscitation and cause-specific control occur together: prepare blood, consider ultrasound, examine when safe and use uterotonics, aspiration, tamponade, embolisation or surgery according to the senior assessment.
Suspected sepsis requires prompt cultures where they do not delay therapy, broad-spectrum intravenous antibiotics and evacuation of infected retained tissue when indicated.
After early home medical abortion, use the supplied low-sensitivity or multi-level urine test; continuing symptoms, little bleeding or a positive result needs service review.
Provide written expected symptoms, a 24-hour contact and exact emergency thresholds before discharge, checking privacy, language, transport and ability to return.
New unilateral pain, shoulder-tip pain, rectal pressure, collapse or peritonism after an abortion before location was proven may be an ectopic pregnancy.
Severe or increasing abdominal pain, guarding, shoulder pain, distension or haemodynamic change after instrumentation can indicate uterine perforation, visceral injury or internal bleeding.
05Cultures, lactate and organ profile
Why
Assess sepsis severity and obtain microbiology without delaying broad-spectrum treatment.
Interpretation and limitations
Normal early tests do not exclude severe infection; repeat physiology and lactate, and use renal and liver results to guide antibiotics and support.
06CT or operative assessment
Why
Identify bowel, bladder, vascular or intra-abdominal injury when perforation is clinically concerning.
Interpretation and limitations
A stable patient may undergo urgent cross-sectional imaging, while shock or peritonism should prompt immediate senior operative decision-making.
2Use examination and ultrasound only when they do not delay treatment, considering atony, retained tissue, laceration, perforation and coagulopathy.
3EscalationEscalate through uterotonics, aspiration, repair, tamponade, embolisation or surgery according to cause, response and local senior expertise.
03SepsisGive antibiotics and achieve source controlPersistent fever, offensive discharge, worsening pelvic pain or systemic deterioration suggests post-abortion infection.+
1Assess sepsis physiology, take cultures, lactate and organ bloods promptly and begin the current broad-spectrum intravenous regimen without avoidable delay.
2Ask senior gynaecology to assess retained infected tissue and arrange uterine evacuation after initial resuscitation when source control is required.
3Monitor response, urine output and organ function closely and involve microbiology and critical care for shock, toxin-mediated features or treatment failure.
04Persistent pregnancy signalDistinguish ongoing, retained and ectopic pregnancyThere was little expected bleeding, symptoms continue or the scheduled pregnancy test remains positive.+
1Review pain, bleeding, initial pregnancy location, medicine adherence and timing, then arrange ultrasound and serial hCG according to clinical risk.
2EscalationEscalate urgently for unilateral pain, shoulder symptoms, peritonism or haemodynamic change because abortion medication does not treat ectopic pregnancy.
3For confirmed ongoing intrauterine pregnancy or retained tissue, discuss repeat medicines, aspiration or expectant care where safe, respecting informed preference.
A range of emotions is common; offer support or counselling when requested and reassure that abortion itself is not associated with increased infertility, breast cancer or mental-health problems.
