Experiencing one miscarriage is heartbreaking. Experiencing two or more can leave you searching for answers.
Recurrent pregnancy loss (RPL) — defined as two or more consecutive miscarriages — affects approximately 5% of couples trying to conceive. While miscarriage is common, repeated pregnancy loss is not something you should ignore or simply “keep trying” through.
The most important thing to know is this: Recurrent miscarriage is often treatable. With advanced fertility diagnostics and personalized care, many patients go on to have healthy pregnancies.
If you’ve been asking, “Why do I keep miscarrying?” — this guide will walk you through the causes, recommended testing, and the most effective treatment options available today.
What Is Recurrent Pregnancy Loss (RPL)?
Recurrent pregnancy loss is medically defined as the loss of two or more confirmed pregnancies before 24 weeks of gestation.
While older guidelines recommended waiting for three miscarriages before evaluation, most fertility specialists now advise testing after two consecutive losses, especially if:
-
You are over age 35
-
You have known medical conditions
-
Losses occurred after seeing a heartbeat
-
You are experiencing infertility in addition to miscarriage
Early evaluation improves the likelihood of identifying a correctable cause.
Why Do I Keep Miscarrying? Common Causes of Recurrent Pregnancy Loss
Understanding the root cause is essential to preventing future pregnancy loss. Below are the most common medical causes of recurrent miscarriage.
1. Chromosomal Abnormalities (Genetic Causes of Miscarriage)
The most common cause of early pregnancy loss is chromosomal abnormalities in the embryo.
Sometimes these abnormalities occur randomly. In other cases, one partner may carry a balanced chromosomal rearrangement (such as a translocation) that increases miscarriage risk.
Treatment Option:
-
IVF with Preimplantation Genetic Testing (PGT-A or PGT-SR)
This allows selection of chromosomally normal embryos, significantly reducing miscarriage risk.
For many patients with genetic-related RPL, IVF with PGT dramatically improves success rates.
2. Hormonal Imbalances That Cause Miscarriage
Hormones play a critical role in implantation and early pregnancy support. Even subtle imbalances can interfere with embryo development.
Common hormonal causes include:
-
Thyroid disorders (hypothyroidism or hyperthyroidism)
-
Low progesterone levels (luteal phase defect)
-
Polycystic ovary syndrome (PCOS)
-
Insulin resistance
-
Elevated prolactin
Treatment Options:
-
Progesterone supplementation
-
Thyroid medication
-
PCOS management
-
Blood sugar regulation
-
Ovulation support
Correcting hormonal issues often significantly reduces miscarriage risk.
3. Uterine Abnormalities That Prevent a Healthy Pregnancy
Structural abnormalities inside the uterus can interfere with implantation or restrict fetal growth.
These include:
-
Uterine septum
-
Fibroids
-
Polyps
-
Intrauterine scar tissue (Asherman’s syndrome)
-
Congenital uterine shape abnormalities
Treatment Option:
-
Minimally invasive hysteroscopic surgery
Correcting uterine abnormalities can restore a normal uterine environment and greatly improve pregnancy outcomes.
4. Autoimmune and Blood Clotting Disorders
Certain autoimmune conditions can interfere with placental development.
The most well-known is antiphospholipid syndrome (APS). Some inherited clotting disorders may also increase miscarriage risk.
Treatment Options:
-
Low-dose aspirin
-
Heparin or other blood thinners
-
Close early pregnancy monitoring
With appropriate treatment, many patients with clotting disorders carry successfully to term.
5. Age-Related Egg Quality Decline
As women age — particularly after 35 — egg quality declines. This increases the likelihood of chromosomally abnormal embryos.
Treatment Options:
-
IVF with genetic testing
-
Fertility preservation strategies
-
Personalized stimulation protocols
Advanced reproductive technology allows us to better select healthy embryos.
6. Unexplained Recurrent Pregnancy Loss
In some cases, no clear cause is identified even after thorough testing. While this can be frustrating, unexplained RPL does not mean there are no solutions.
Enhanced monitoring, immune-modulating strategies, and embryo testing can still improve outcomes.
What Testing Should Be Done After Two Miscarriages?
If you’ve experienced multiple losses, a comprehensive recurrent pregnancy loss workup is recommended.
This typically includes:
-
Detailed reproductive history review
-
Hormone testing (thyroid, progesterone, insulin, prolactin)
-
Ovarian reserve testing
-
Genetic carrier screening for both partners
-
Karyotype analysis
-
Uterine imaging (saline ultrasound or hysteroscopy)
-
Autoimmune and clotting panel
-
Metabolic screening
The goal is to identify a treatable cause and create a targeted plan.
How to Prevent Recurrent Miscarriage: Evidence-Based Treatments
Preventing miscarriage depends on addressing the underlying issue. Treatment may include:
✓ IVF with Preimplantation Genetic Testing (PGT)
Screens embryos for chromosomal normality before transfer.
✓ Progesterone Support
Strengthens the uterine lining and supports implantation.
✓ Surgical Correction of Uterine Abnormalities
Removes structural barriers.
✓ Blood Thinner Therapy
Improves placental blood flow.
✓ Hormone Optimization
Balances thyroid and metabolic function.
✓ Early Pregnancy Monitoring
Frequent ultrasounds and lab work during early pregnancy provide reassurance and allow immediate intervention.
Many patients with recurrent pregnancy loss achieve successful live births after appropriate treatment.
What Are the Success Rates After Recurrent Pregnancy Loss?
Success rates depend on age and underlying cause. However:
-
Patients with correctable uterine abnormalities often see dramatic improvement.
-
IVF with PGT significantly reduces miscarriage risk related to chromosomal issues.
-
Patients treated for clotting disorders frequently carry to term.
With a personalized fertility plan, the outlook after RPL is far more hopeful than many patients initially believe.
The Emotional Impact of Recurrent Miscarriage
Repeated pregnancy loss affects emotional well-being as much as physical health.
Common feelings include:
-
Anxiety after a positive pregnancy test
-
Fear of attachment
-
Depression or grief
-
Relationship strain
-
Loss of trust in your body
Compassionate fertility care includes emotional support. Counseling, support groups, and a responsive medical team can make a significant difference during this journey.
You are not alone. And you did not cause this.
When Should You See a Fertility Specialist for Recurrent Miscarriage?
You should schedule an evaluation if:
-
You’ve had two or more consecutive miscarriages
-
You are over 35 with one miscarriage
-
You have a history of infertility
-
You want proactive answers before trying again
Early evaluation provides clarity and improves future outcomes.
Frequently Asked Questions About Recurrent Pregnancy Loss
Can I have a healthy baby after multiple miscarriages?
Yes. Many patients with RPL go on to have successful pregnancies with proper diagnosis and treatment.
Should I try naturally again or consider IVF?
This depends on your diagnosis, age, and reproductive goals. Genetic testing through IVF may significantly reduce risk in some patients.
Does stress cause recurrent miscarriage?
There is no strong evidence that stress alone causes miscarriage. Most recurrent losses are due to medical factors.
How long should I wait after miscarriage before trying again?
This depends on physical recovery and your treatment plan. A fertility specialist can guide you.
