Recurrent Miscarriages. Habitual Abortion. Repeated Pregnancy Losses
If you have found yourself holding your breath every time you see a faint positive line on a pregnancy test, if you have already experienced the heartbreak of losing a pregnancy once, twice, or even more, and if every new attempt fills you with hope and dread in equal measure: you are not alone. The pain of recurrent miscarriages is a hidden burden that many couples silently carry. At Malpani Infertility Clinic, we meet women and couples every week who feel this exact mix of fear, grief, and uncertainty. We know you want honest answers, sensible guidance, and above all: someone who will not dismiss your pain, or put you through meaningless tests and treatments. Let us walk you through what you need to know, and what you can do next.
Understanding Recurrent Miscarriages
In medical terms, a miscarriage is called an abortion. Most miscarriages start with a bit of vaginal bleeding, often painless at first. This is known as a threatened abortion: the pregnancy is at risk, but not yet lost. Many times, the bleeding stops on its own, and the pregnancy continues. At this stage, an ultrasound scan, usually done with a vaginal probe, can be your best friend. If the scan shows a fetal heartbeat, there is a 95 percent chance your pregnancy will proceed normally.
But sometimes, the ultrasound reveals that the fetus has not developed as it should. If there is no visible fetus (a "blighted ovum"), or if the heart is not beating, unfortunately, nothing can be done to save the pregnancy. The bleeding may get worse, cramps start, and the cervix opens. If some of the pregnancy tissue is already expelled, it is called incomplete abortion. When these losses happen two or more times in a row, doctors use the term recurrent pregnancy loss (RPL), also known as habitual abortion or repeated pregnancy loss.
Recurrent miscarriage can be one of the most frustrating problems in fertility medicine. Not only is there still much we do not understand, but the emotional toll on would-be parents is enormous.
Abortions that occur in the first 12 weeks are called first trimester abortions. Those between 13 and 20 weeks are called second trimester abortions. Most miscarriages, around 80 percent, happen in the first trimester.
How Common Is Recurrent Miscarriage?
You might be surprised to learn that 20 to 30 percent of all women experience spotting, bleeding, or cramps during their first twelve weeks of pregnancy. About 10 percent will have a miscarriage. Many more may not even realize they were pregnant, mistaking an early loss for a late or heavy period.
of women experience recurrent pregnancy loss, defined as two or more consecutive miscarriages.
The most common cause of a first trimester miscarriage is a random genetic defect in the embryo. Nature often acts as a quality control mechanism, preventing the birth of babies with severe abnormalities. Most women who miscarry once will go on to have a healthy pregnancy next time, without any intervention.
- Most women who miscarry do so only once. Their risk of miscarrying again is not higher than average, about 15 percent.
- Women over 35 are more likely to miscarry due to age-related changes in egg quality.
- Travel, exercise, lifting weights, and sex do not cause miscarriage. As the saying goes, you cannot shake a good apple off a tree.
- If you have had a miscarriage, anxiety in the next pregnancy is very common, but bed rest or avoiding work does not prevent loss.
After two or more consecutive miscarriages, the risk of another miscarriage increases, but it is still more likely that your next pregnancy will succeed. For example, after two losses, the chance of miscarriage rises to about 30-35 percent, which still means there is a 65-70 percent chance of a healthy pregnancy next time.
Why Do Recurrent Miscarriages Happen?
This is the question every couple asks, and unfortunately, even after thorough evaluation, no clear cause is found in about half of all cases. However, there are some well-recognized reasons:
- Genetic (chromosomal) abnormalities: Sometimes, one parent carries a rearrangement in their chromosomes that increases the risk of miscarriage. Both partners can have a karyotype blood test to check this.
- Hormonal imbalances: Thyroid disorders, uncontrolled diabetes, and conditions like polycystic ovary syndrome (PCOS) can play a role.
- Structural problems in the uterus: Abnormalities like a uterine septum, fibroids, or adhesions make it harder for a pregnancy to continue. These can often be detected with tests like hysterosalpingogram or hysteroscopy.
- Antiphospholipid antibody syndrome: An immune system problem where the body’s own antibodies attack the pregnancy. This is tested by specific blood tests.
- Polycystic ovary syndrome (PCOS): Women with PCOS have a higher risk, possibly due to hormonal imbalances and insulin resistance.
- Other health conditions: Such as poorly controlled thyroid or diabetes, or rare blood-clotting disorders.
- Age-related changes (oopause): As women get older, egg quality drops, increasing the risk of genetic abnormalities.
- Lifestyle factors: Smoking, high alcohol use, and being underweight or obese can have an effect.
It’s natural to wonder if the sperm might be to blame. While sperm do contribute half the genes, studies show that abnormal sperm counts or shapes are not linked to recurrent miscarriage or failed IVF.
Sometimes, despite every test, no clear reason is found; this does not mean you did anything wrong or that you cannot have a healthy baby.
The Emotional Cost of Loss
What most people do not realize is that a miscarriage is not just a medical event. To parents, the fetus is already a baby. You have probably seen the heartbeat on a scan, pictured the future, and started loving your child. Losing a pregnancy can feel like a personal bereavement, and the grief is real, especially if you have struggled with infertility for a long time.
Sadly, society often brushes this grief aside, treating miscarriage as a non-event. But your pain is valid. It is normal to feel sadness, anger, isolation, and even guilt. Healing is possible, but it takes time. Support from your partner and from others who have experienced similar loss can help. Do not hesitate to reach out for help or counseling if you need it.
You may find that the thought of trying again fills you with anxiety. It is common to feel both hope and fear, and there is no "right" time to start the process again. The decision is deeply personal, and only you and your partner can know when you are ready.
Testing After Recurrent Miscarriages
If you have had two or more miscarriages, it is reasonable to begin testing to look for treatable causes. Here are the tests that have proven value:
- Hysterosalpingogram or hysteroscopy: To check for uterine problems like fibroids, septum, or scarring.
- Blood tests for antiphospholipid antibodies (lupus anticoagulant): To rule out immune system disorders.
- Karyotype for both partners: To check for chromosomal rearrangements.
- Thyroid function tests: Thyroid disease is a common, correctable cause.
- Blood sugar testing: Especially if you have a history of diabetes or symptoms.
Sometimes, doctors may send the tissue from a miscarriage for genetic testing, but this rarely changes your treatment choices.
Many clinics may suggest a long list of exotic blood tests, including so-called "immune panels" or "TORCH tests" for infections. The truth is, these rarely provide useful information. You can read more about which tests truly matter at this resource and about why immune testing is a waste of time and money at this article.
When to start testing is up to you. After one miscarriage, your chances of a healthy pregnancy next time are better than 85 percent, so most doctors wait until after two losses. But if you are over 35, have had trouble conceiving, or the losses happened after seeing a heartbeat, earlier testing may be worthwhile.
If no treatable cause is found, the most honest answer is also the hardest: sometimes, the only way forward is to try again. Even after three miscarriages, your chance of a successful pregnancy next time is more than 50 percent, sometimes higher with careful support.
The decision to try again is deeply personal. Give yourself time and space to heal before moving forward.
When you do get pregnant again, ask for close monitoring. Early scans and check-ups can offer reassurance. It is understandable to feel anxious and vulnerable, but remember, you are not alone in this journey.
Be kind to yourself as you welcome the next chapter, even if it is filled with mixed emotions. Grieving the loss and celebrating new life can co-exist; both are part of your story.

Frequently Asked Questions
Q: How many miscarriages are considered "recurrent"?
A: Recurrent miscarriage is usually defined as two or more consecutive pregnancy losses, though some guidelines use three. After two losses, it's reasonable to begin evaluation.
Q: What causes repeated miscarriages?
A: Common causes include genetic abnormalities, hormone imbalances, uterine structural problems, immune system disorders like antiphospholipid antibody syndrome, and age-related changes. In about half of cases, no cause is found.
Q: Can lifestyle choices or stress cause miscarriage?
A: Everyday activities like travel, exercise, and sex do not cause miscarriage. Smoking, excessive alcohol, and extremes of weight can increase risk, but most miscarriages are due to factors beyond your control.
Q: What tests should be done after recurrent pregnancy loss?
A: Recommended tests include hysteroscopy or hysterosalpingogram for the uterus, blood tests for antiphospholipid antibodies, thyroid function, karyotyping for both partners, and sugar levels. Avoid expensive or unnecessary immune and infection panels unless specifically indicated.
Q: What are my chances of a healthy pregnancy after recurrent miscarriages?
A: Even after three miscarriages, more than half of women will carry the next pregnancy to term. The outlook is better than most people fear, especially if no treatable cause is found.
Q: When should I try again after a miscarriage?
A: This is a personal decision. Medically, as soon as you and your partner feel emotionally ready, you can try again. There is no evidence that waiting longer improves outcomes, unless you need time to heal or complete testing.
Q: Does a man's sperm quality cause recurrent miscarriage?
A: Most studies show no link between abnormal sperm and repeated miscarriages. Genetic factors may sometimes be involved, but routine sperm "quality" is not usually the cause.
Q: Can recurrent miscarriage be prevented?
A: Some causes, like hormonal imbalances or uterine issues, can be treated. For many, the best approach is supportive care and close monitoring in the next pregnancy. Most women will have a healthy baby in the end.
