What recurrent miscarriage is
Recurrent miscarriage is usually defined as the loss of two or more pregnancies, although some clinicians use a threshold of three. Whatever the number, if you are reading this after more than one loss, please know that what you are feeling is understandable. Miscarriage on its own is a painful experience; going through it again, and perhaps again, can bring a very deep kind of grief, along with fear about the future and questions that may feel impossible to answer. This is one of the most emotionally difficult experiences a couple can face, and there is no right or wrong way to feel about it. The purpose of assessment is not to reduce your loss to a set of test results, but to look gently and carefully for anything that can be treated, and to support you towards a healthier pregnancy if that is what you hope for.
An important, reassuring message
If you take only one thing from this guide, let it be this: even after recurrent miscarriage, many couples go on to have a successful pregnancy, particularly with the right assessment and supportive care. In the great majority of cases, recurrent miscarriage is not caused by anything you did or did not do. It is not caused by ordinary activity, by working, by exercising sensibly, by lifting your other children, by stress at the office, by a meal you ate, or by intimacy. It is not a punishment, and it is not a failing. Miscarriage is common, and often reflects factors that are simply outside anyone’s control. Many people carry quiet, private guilt after a loss, and if that is you, we hope you can begin to set it down. A doctor can help you understand what is known about your own situation, and in many couples the outlook for a future pregnancy remains genuinely hopeful.
Possible causes
One of the hardest parts of recurrent miscarriage is that, in many couples, no single cause is ever found. This can feel deeply unsatisfying, but it is important to say clearly that “no cause found” is not the same as “no hope” — the outlook for these couples is often good. Where a recognised factor is present, it may include:
- Chromosomal factors — a chance chromosomal problem in the pregnancy is a common reason for an individual miscarriage. Less often, one partner carries a rearrangement in their own chromosomes that is passed on.
- Antiphospholipid syndrome — a blood-clotting condition in which the immune system makes antibodies that raise the tendency to clot, which can affect the placenta. It is one of the most important treatable causes to look for.
- Problems with the shape of the womb — certain differences in the structure of the uterus, present from birth or acquired later, can make it harder to carry a pregnancy.
- Hormonal and metabolic factors — such as thyroid problems or poorly controlled diabetes, and conditions such as PCOS.
- Increasing maternal age — the risk of miscarriage rises with age, largely because of the increasing chance of chromosomal problems in the egg; this is a matter of biology, not of anything done wrong.
Lifestyle factors such as smoking are also worth addressing, but for most couples the causes lie well beyond the small daily choices people often blame themselves for. It is also worth knowing that a single miscarriage, and even two, can happen purely by chance in someone who will go on to have healthy pregnancies; recurrence does not automatically mean something is “wrong” with you or your partner. Assessment simply gives you the clearest picture available, so that any factor that can be helped is not missed.
What investigations may be offered
Because early miscarriage is common, investigations are usually offered after two or three losses, so that testing is focused and meaningful. Seeing a gynaecologist or fertility specialist also allows you and your partner to be assessed together, as a couple, with time to ask questions. Testing is guided by your history, and may include:
- Blood tests — including tests for antiphospholipid syndrome (usually repeated to confirm) and thyroid function, and other hormone or metabolic tests where relevant.
- Imaging of the womb — a pelvic ultrasound, and sometimes further imaging, to look at the shape and structure of the uterus.
- Genetic tests — of the couple, and where available of the pregnancy tissue, to look for chromosomal factors.
Not everyone needs every test, and it is quite normal for results to come back reassuringly normal. Your specialist can explain what each test is looking for and what the results mean for you.
Treatments and management
Treatment depends on what, if anything, is found — there is no single remedy that suits everyone, and being wary of clinics promising guaranteed answers is wise. Where a cause is identified, care is tailored to it:
- Antiphospholipid syndrome is typically managed with blood-thinning treatment (classes such as low-dose aspirin and a heparin, started in early pregnancy under specialist care), which can improve the chance of a successful pregnancy.
- Thyroid or blood-sugar problems are treated by correcting and stabilising them, ideally before and during pregnancy.
- Certain womb abnormalities may be helped by surgery, where a specialist judges it appropriate.
Alongside any specific treatment, supportive early-pregnancy care — closer monitoring, reassurance scans, and a clear point of contact — is valued by many couples in a subsequent pregnancy. And here is the honest, hopeful part worth repeating: when no cause is found, supportive care in early pregnancy still offers good odds of a successful outcome. In Singapore, your GP or polyclinic can arrange referral, and specialist units at hospitals such as KKH and NUH are experienced in caring for couples through recurrent loss.
Emotional wellbeing and support
Recurrent miscarriage is not only a medical matter; it is a genuine bereavement, and the grief that comes with it is real and valid. You may feel sadness, anger, numbness, anxiety about trying again, or a sense of being alone even in a room full of people — and these feelings can come and go for a long time, sometimes surfacing on due dates or anniversaries. There is no timetable for grief, and no amount of loss is “too small” to mourn. It is worth remembering, too, that partners are affected. They may grieve differently or more quietly, and each of you may need support in your own way. Talking to your doctor about how you are coping is not a distraction from medical care but a part of it. Counselling and peer support groups help many couples feel less isolated, and resources through HealthHub and hospital counselling services can point you towards support in Singapore. Some people find comfort in talking to others who have walked the same path, while others prefer a professional counsellor, and either is a valid choice. You are also allowed to take a break from trying, to grieve at your own pace, and to decide together what feels right for your family — there is no obligation to have a plan, or to “stay strong”, before you are ready. If at any point you feel unable to cope, or have thoughts of harming yourself, please reach out to a doctor, a trusted person, or a local helpline without delay — you deserve support.
When to see a doctor
Consider asking your GP or polyclinic for referral to a gynaecologist or fertility specialist after two or three miscarriages, or earlier if you already know you have a risk factor, so that investigations and a supportive plan can be arranged before your next pregnancy.
Separately, during a pregnancy or a miscarriage itself, some symptoms need urgent attention. Please seek urgent care — go to A&E, or call 995 — if you have very heavy vaginal bleeding (for example soaking through pads quickly or passing large clots), severe or worsening tummy pain, a fever, or if you feel faint, dizzy or unwell. These can be signs that need prompt assessment, and it is always right to get checked rather than wait.
Common questions
How many miscarriages before I should be investigated?
Investigation is usually offered after two or three losses, and sometimes earlier if there is a known risk factor.
Will I be able to have a baby?
Many couples with recurrent miscarriage go on to have a successful pregnancy, even when no cause is found.
Is recurrent miscarriage my fault?
No. Miscarriage is common and usually reflects factors outside your control; investigation aims to find any treatable cause.
