Recurrent Pregnancy Loss: Causes, Testing, and Hope
Understanding why this happens, what can be done, and finding your path forward after multiple miscarriages.
Recurrent pregnancy loss (RPL) is defined as two or more pregnancy losses. It affects about 1-2% of couples trying to conceive. Importantly: even after 3 losses with no treatment, 60-70% of couples will have a successful pregnancy. Testing can identify causes in about 50% of cases, and treatment is available for many of them.
First: Your Grief Is Valid
Multiple losses are devastating. Each one carries its own grief, and the cumulative weight can be crushing. You may feel broken, betrayed by your body, terrified to hope again.
These feelings are normal. You're not weak for struggling. You're not "overreacting" because losses were early. Each pregnancy represented hope and possibility—and losing that, repeatedly, is profound.
Before diving into causes and treatments: take time to grieve. Seek support. This is hard.
What Causes Recurrent Loss?
Testing for Recurrent Loss
If a miscarriage occurs, testing the tissue for chromosomal abnormalities (products of conception testing, or POC) can be valuable. If the loss was chromosomally abnormal, that explains it—and suggests the next pregnancy may be different. If chromosomally normal, that points toward other causes. Ask about this testing if you experience another loss.
Treatment Options
For Identified Causes
- Antiphospholipid syndrome: Baby aspirin + heparin/Lovenox during pregnancy—this significantly improves success rates (from ~20% to ~70%+)
- Uterine abnormalities: Surgical correction (septum resection, fibroid/polyp removal)
- Thyroid disorders: Medication to optimize levels before and during pregnancy
- Parental translocation: IVF with PGT-SR (testing embryos for the specific chromosomal issue)
- Progesterone deficiency: Progesterone supplementation (though evidence is mixed for this indication)
For Unexplained RPL
When no cause is found, options include:
- Supportive care: Close monitoring, early ultrasounds, emotional support—studies show supportive care alone improves outcomes in unexplained RPL
- Progesterone supplementation: Often prescribed even without proven deficiency; low risk, possible benefit
- IVF with PGT-A: If chromosomal issues in embryos are suspected, testing embryos before transfer may help select chromosomally normal ones
- Empirical treatments: Some doctors try aspirin, steroids, or intralipids—evidence is limited, and these should be discussed carefully
Even after 3-4 losses with no treatment, 60-70% of couples will eventually have a successful pregnancy. After 2 losses, that number is even higher. Your odds are better than they may feel right now. Don't give up.
Trying Again After Loss
There's no required waiting period after most early losses—you can try as soon as you feel physically and emotionally ready. Some doctors recommend waiting one cycle for dating purposes.
Emotionally, "ready" looks different for everyone. Some need time; others find trying again helps them cope. Both are valid.
When you do conceive again, early monitoring (early ultrasounds, beta hCG tracking) can provide reassurance—or early information if things aren't progressing.
Frequently Asked Questions
No. Miscarriage is almost never caused by anything you did—exercise, sex, stress, that glass of wine before you knew. Most losses are due to chromosomal issues in the embryo that happen randomly. Please don't carry blame for something that was never in your control.
One loss is common (~15-20% of known pregnancies) and usually doesn't require specialized testing. After two losses, ACOG recommends evaluation. Some doctors will begin testing after one loss if there are risk factors or if you're over 35 and want answers sooner. Advocate for yourself if you feel testing is warranted.
Statistics say: very likely yes. Even after multiple losses, the majority of couples eventually succeed—whether through continued trying, treatment, or alternative paths like donor gametes or surrogacy. There may be more loss ahead, but there is also real hope for success.
Pregnancy after loss is anxiety-filled—this is normal. Strategies: therapy (especially with someone who understands pregnancy loss), support groups, early monitoring for reassurance, mindfulness practices, and giving yourself permission to feel both hopeful and scared. You don't have to "relax"—you just have to get through one day at a time.
Yes. Grief is deeply personal. One partner may cry openly while the other goes quiet. One may want to talk constantly; another may need distraction. Neither is wrong. Try to give each other grace, communicate about what you need, and consider couples counseling if you're struggling to connect.
The Bottom Line
Recurrent loss is heartbreaking—but it's not hopeless. Testing can identify causes in many cases, and treatments exist. Even when no cause is found, the odds of eventual success remain high.
You are not broken. Your body is not failing you. Sometimes biology is cruel in ways that have nothing to do with your worth or your future as a parent.
Keep going if you can. Seek support. And know that many, many people who've walked this path are now holding their babies.
