Recurrent Miscarriage Treatment: Causes, Tests and Care
Quick answer: Recurrent miscarriage (recurrent pregnancy loss) is the loss of two or more pregnancies before 24 weeks. Treatment depends on the cause found through tests for antiphospholipid syndrome, uterine shape problems, chromosomal changes in either partner, thyroid disease and diabetes. Even when no cause is found, most couples go on to have a successful pregnancy with supportive early-pregnancy care.
Key takeaways
- Recurrent pregnancy loss (RPL) affects around 1–3% of couples trying to conceive.
- Most single miscarriages happen because of a chance chromosomal error in the embryo; repeated losses deserve a structured evaluation.
- Treatable causes include antiphospholipid syndrome, a uterine septum, and thyroid or sugar imbalance.
- In about half of couples no cause is found, and the outlook is still encouraging.
- Close monitoring and emotional support in the next pregnancy make a real difference.
What is recurrent pregnancy loss?
Recurrent pregnancy loss means two or more pregnancy losses before 24 weeks of pregnancy. ESHRE guidelines count losses that need not be consecutive, while some older definitions required three in a row.
Miscarriage is common: about one in eight to one in five recognised pregnancies ends in miscarriage, and the risk rises with the woman’s age. Losing more than one pregnancy is painful, and it is natural to want answers. A careful evaluation can find a cause in some couples and, just as importantly, reassure those in whom no cause is found.
Who should be evaluated for recurrent miscarriage?
- Couples who have had two or more pregnancy losses.
- Women who have had one loss after 10 weeks with a normally developing baby.
- Women aged 35 or over, or those with fertility concerns, after even one loss.
- Women with a known condition such as lupus, thyroid disease, diabetes or PCOS.
What causes recurrent miscarriage?
| Cause | What it means |
|---|---|
| Chromosomal abnormalities in the embryo | The most common cause of individual losses, more frequent with age |
| Parental chromosomal rearrangement | A balanced translocation in either partner, found in a small proportion of couples |
| Antiphospholipid syndrome (APS) | An autoimmune condition that causes clotting in the placenta |
| Uterine anomalies | A septate uterus, submucous fibroids, polyps or adhesions |
| Endocrine factors | Untreated thyroid disease, poorly controlled diabetes, high prolactin, PCOS |
| Cervical weakness | A cause of later (second-trimester) loss, usually painless |
| Lifestyle factors | Smoking, heavy alcohol, obesity and high caffeine intake |
How is recurrent miscarriage investigated? Step by step
- Detailed history. Timing and details of each loss, medical conditions, medicines and family history.
- Blood tests. Antiphospholipid antibodies (lupus anticoagulant, anticardiolipin and anti-β2-glycoprotein), repeated after 12 weeks if positive; thyroid function and antibodies; HbA1c; prolactin where indicated.
- Uterine assessment. 3D ultrasound, with hysteroscopy if an abnormality is suspected.
- Genetic testing. Testing of pregnancy tissue where possible, and karyotyping of both partners when indicated.
- Male assessment. A semen analysis and, in some couples, a sperm DNA fragmentation test.
- Care plan. Results are explained together, with a plan for the next pregnancy.
What are the treatment options for recurrent miscarriage?
- Antiphospholipid syndrome: low-dose aspirin with heparin injections during pregnancy, which improves live-birth rates.
- Uterine septum, polyps or adhesions: hysteroscopic correction.
- Thyroid disease or diabetes: getting levels into the target range before conception.
- Parental chromosomal rearrangement: genetic counselling; options include natural conception with close monitoring or IVF with genetic testing of embryos.
- Bleeding in early pregnancy after a previous miscarriage: vaginal progesterone may be offered, in line with current evidence.
- Cervical weakness: serial cervical-length scans and, if needed, a cervical stitch.
- Unexplained RPL: supportive care, early reassurance scans and lifestyle changes; routine immune or steroid treatments are not recommended.
What are the chances of a successful pregnancy?
The outlook is encouraging. Even after several losses, most couples have a successful pregnancy, especially when the woman is younger and the number of previous losses is smaller. Studies of couples with unexplained RPL show that supportive care and early scans are associated with good outcomes.
Risks, side effects and aftercare
Aspirin and heparin can cause bruising at injection sites and, rarely, bleeding. Hysteroscopy causes mild cramping and spotting for a day or two. After a miscarriage, most women can try again once they feel emotionally ready and have had one normal period. Take folic acid, avoid smoking and alcohol, keep caffeine low, and book an early scan at around six to seven weeks in your next pregnancy.
What does RPL evaluation cost?
Costs depend on which blood tests and genetic tests are required, whether a 3D scan or hysteroscopy is needed, medicines in the next pregnancy, and the number of monitoring visits. Tests are chosen step by step, based on your history.
When to see a doctor
Seek a review after two miscarriages, or after one if you are over 35 or have fertility concerns. In early pregnancy, seek urgent care for heavy bleeding, severe one-sided pain, shoulder-tip pain, dizziness or fainting, which can signal an ectopic pregnancy.

Frequently Asked Questions
What tests are done after recurrent miscarriages?
Antiphospholipid antibodies, a uterine evaluation (3D ultrasound or hysteroscopy), thyroid function and antibodies, blood sugar, prolactin where indicated, and karyotyping of both partners or the pregnancy tissue in selected cases.
What are the chances of a successful pregnancy after RPL?
Encouraging. Even after several losses, most couples have a successful pregnancy with appropriate investigation, treatment and close early-pregnancy support.
When should I seek help after a miscarriage?
After two miscarriages, or after one miscarriage if you are over 35 or already have fertility concerns.
Does progesterone prevent miscarriage?
Vaginal progesterone may help women who have bleeding in early pregnancy and have had a previous miscarriage. It is not a treatment for every woman with recurrent loss, so your doctor will advise whether it suits you.
Did stress or work cause my miscarriage?
Normal daily activity, work, exercise and intercourse do not cause miscarriage. Most early losses are due to chance chromosomal errors in the embryo.
Should I try again soon after a miscarriage?
Most women can try again after one normal period, once they feel emotionally ready. If you have had recurrent losses, complete the evaluation first so a plan is in place.
