When a pregnancy ends unexpectedly, it can feel as though time stands still. When it happens more than once, the questions become harder to ignore.

Why did this happen? Could it happen again? And perhaps most importantly, what can be done next?

The reassuring news is that international medical understanding of recurrent pregnancy loss has advanced significantly in recent years. With careful evaluation and supportive care, many couples go on to have healthy pregnancies.

This article explores the possible causes of recurrent pregnancy loss, the tests that may be recommended, and the next steps that can help you achieve the best possible outcomes.

What is Recurrent Pregnancy Loss?

Recurrent pregnancy loss generally refers to the loss of two or more pregnancies before 24 weeks of gestation. It affects a small percentage of couples, around 1 in every 100 couples, the emotional impact can be profound. It is important to remember that miscarriage is common and, in many cases, occurs because of factors beyond anyone’s control. Experiencing more than one loss does not automatically mean there is a serious underlying problem, but it may warrant further investigation.  

Possible Causes of Recurrent Pregnancy Loss

Recurrent pregnancy loss can have several contributing factors. In many cases, there is no single cause. Understanding the possible medical and lifestyle influences can help guide evaluation and support.

• Genetic factors – The most common reason for miscarriage, especially in early pregnancy, is a chromosomal abnormality in the embryo. These abnormalities typically occur randomly at the time of fertilisation and are not usually inherited. The risk of such chromosomal changes increases with maternal age. In a smaller number of cases, one partner may carry a chromosomal rearrangement, which can raise the risk of repeated pregnancy loss.
• Structural differences in the uterus  – The shape and structure of the uterus can sometimes affect implantation or the ability to maintain a pregnancy. These may include a uterine septum, intrauterine adhesions, or fibroids.
• Hormonal imbalances – Certain medical conditions are associated with an increased risk of miscarriage if left untreated. These include thyroid disorders and poorly controlled diabetes. Identifying and managing these conditions before conception or during early pregnancy can form an important part of fertility care.
• Antiphospholipid Syndrome (APS) – Antiphospholipid syndrome is an autoimmune condition that can increase the risk of recurrent miscarriage and pregnancy complications. Because it is one of the few immune-related conditions with clear evidence linking it to recurrent pregnancy loss, testing for APS is routinely recommended during specialist assessment.
• Other factors –  Lifestyle factors, overall health and, in selected cases, aspects of sperm quality may also be considered as part of a comprehensive evaluation. 

When Should You Seek Medical Advice?

After experiencing repeated pregnancy loss, seeking medical guidance can help you better understand your condition. Many specialists recommend evaluation after two losses, especially if you are planning to conceive again.

A fertility specialist can review your medical history, prior pregnancies, and any existing health conditions before recommending further testing.

Early consultation often helps couples feel supported and informed as they explore the next steps.

Tests That May Help Identify Causes

A thorough fertility assessment may include several diagnostic tests. These evaluations aim to identify factors that could affect pregnancy and guide appropriate treatment.

When recurrent pregnancy loss is identified, a structured evaluation may be recommended to help identify any underlying causes. Depending on your medical history, this may involve:

• A detailed review of your medical and reproductive history, including previous pregnancies, miscarriages, live births, and any relevant health conditions.
• Assessment of the uterus, usually through ultrasound and, in selected cases, hysteroscopy, to evaluate its shape and structure.
• Blood tests to assess clotting, including antiphospholipid antibodies such as lupus anticoagulant and anticardiolipin antibodies.
• Thyroid function screening, including TSH and thyroid peroxidase (TPO) antibodies. 
• Genetic testing in selected cases, rather than as a routine investigation for all couples.

All investigations are guided by clinical evidence and tailored to each individual. Our approach is careful and considered, ensuring you are fully informed and supported throughout the process, without feeling rushed.

Understanding Your Next Steps

For some couples, investigations identify a clear factor that can be addressed. For others, results may be entirely normal.

While this uncertainty can feel frustrating, it is worth remembering that many couples with unexplained recurrent pregnancy loss still achieve a successful pregnancy.

Depending on the findings, your care plan may include:

• Optimising treatment for existing medical conditions, such as thyroid disease or diabetes
• Medication in a future pregnancy if antiphospholipid syndrome is diagnosed
• Surgical treatment for selected uterine abnormalities, where clinically appropriate
• Genetic counselling if chromosomal factors are identified
• Supportive early pregnancy care, which may include early scans and specialist follow-up

Personalised care plans are designed to support both physical health and emotional wellbeing throughout the process.
