Recurrent Miscarriage
Clinical detail
Additional detail checked 2026-10-17 against the linked sources. This check covers the section below; the rest of the module retains its displayed verification status.
A recurrent-loss consultation should review the pattern of previous pregnancies, possible causes and support for the next pregnancy. Unexplained recurrent miscarriage is common and does not mean that a successful pregnancy is unlikely.
Assessment & interpretation
- RCOG defines recurrent miscarriage as three or more early losses; they do not have to be consecutive.
- Review previous imaging and tissue results. Offer uterine assessment, thyroid testing and an antiphospholipid-antibody evaluation; select other endocrine or genetic tests from the history and prior results.
- Confirmation of antiphospholipid syndrome requires positive tests at least 12 weeks apart and at least 6 weeks after a miscarriage.
Decisions that change management
- Confirmed antiphospholipid syndrome has a different treatment pathway from unexplained loss. Routine treatment of inherited thrombophilia has not demonstrated the same benefit.
- A previous miscarriage plus bleeding in a new pregnancy warrants assessment for the guideline-supported progesterone pathway. Progesterone is not a universal treatment for asymptomatic unexplained recurrent loss.
Follow-up & safety-netting
- Offer a clear contact plan, supportive early-pregnancy care and scans where appropriate.
- Discuss smoking, alcohol, caffeine and weight without attributing blame. Include emotional wellbeing and the needs of the partner.
Admission & discharge
Admission/discharge guidance checked 2026-10-18 against the linked sources. This is a clinical checklist for an individual decision, not an automatic discharge order.
When admission or continued hospital care is needed
- Current heavy bleeding, instability, infection or severe pain follows the acute miscarriage/ectopic pathway; urgent mental-health assessment is needed for immediate safety concerns.
When clinic, day care or home care may be suitable
- A history of recurrent miscarriage without an acute complication does not itself require admission. Arrange supportive early-pregnancy and specialist assessment.
Before going home
- Any current acute event has been assessed and safely managed; provide a named supportive-care route and an investigation/result plan.
Discharge medicines and treatment changes
- Continue only treatment indicated for the current pregnancy/diagnosis; do not prescribe anticoagulation or progesterone for every history of miscarriage without eligibility.
Tests, pending results and their reviewer
- Assign review of indicated investigations and any pending histology/genetic results; avoid repeating a broad panel without a clinical reason.
Home care and counselling
- Discuss grief support, planning another pregnancy and how to access early scanning/support if pregnancy occurs.
Follow-up: when and what to review
| When | Action / responsible service |
|---|---|
At the booked specialist review | Review results, possible causes and a written plan for the next pregnancy. |
With a new positive pregnancy test | Contact the early-pregnancy/support service promptly for the agreed assessment plan. |
Return urgently
- Heavy bleeding, severe/unilateral pain, collapse, fever or inability to remain safe requires urgent help.

Treatment
① Immediate stabilization — first minutes
Not an emergency pathway — structured preconception clinic.
③ First-line treatment & drug regimens
- APS confirmed: low-dose aspirin 75–100 mg + prophylactic LMWH from positive test (live-birth benefit ~50%+)
- NICE: vaginal micronised progesterone 400 mg twice daily for bleeding with a previous miscarriage once an intrauterine pregnancy is confirmed on scan; if fetal heartbeat confirmed, continue until 16 completed weeks
- Genetic: product karyotyping each loss; PGTA counselling where balanced translocation
- Untreated/unexplained: supportive early-pregnancy scanning programme (reassurance scans improve outcomes modestly)
Monitoring
- Early viability scans 6–8 wks
- APS: platelet counts on LMWH; BP surveillance
Escalation
- Reproductive immunology/experimental therapies (intralipid, steroids unselected) NOT recommended outside research
⑮ Complications & their management
Late losses
Consider cervical-length screening for cerclage indications (history-indicated if classic prior mid-trimester loss)
Post-treatment care
- Psychological support integral
- Document cumulative live-birth rates (~65–75% overall with support)
Diagnosis & assessment
Definition: RCOG defines recurrent miscarriage as three or more first-trimester miscarriages; they need not be consecutive. Clinical context may justify earlier assessment.
Investigations
| Test | Looking for |
|---|---|
Antiphospholipid panel (lupus anticoagulant + anticardiolipin + anti-β2GPI ×2, 12 wks apart) | APS — the one clearly treatable cause |
Parental peripheral karyotypes | Balanced translocations (~2–5% of couples) |
TSH, HbA1c/OGTT, PCOS screen, prolactin | Endocrine contributors |
Pelvic ultrasound ± 3D/hysteroscopy | Uterine anomalies/polyps/fibroids |
Thrombophilia testing NOT routine (factor V Leiden etc.) | Contested utility outside APS |
