Miscarriage remains one of the most emotionally challenging experiences a person can face during pregnancy. In the UK, it is estimated that one in four pregnancies ends in miscarriage, a statistic that highlights both the urgency and importance of better prevention, support, and early intervention. Now, the Tommy’s National Centre for Miscarriage Research has taken a major step forward with the launch of the Tommy’s miscarriage risk calculator — a first-of-its-kind online tool designed to help women and pregnant people understand their personal risk and receive the right support at the right time.
This new miscarriage support tool UK is set to change how early pregnancy care is delivered by offering a more tailored approach to miscarriage prevention and guidance.
What Is Tommy’s Miscarriage Risk Calculator?
The Tommy’s miscarriage risk calculator is an online miscarriage risk assessment tool that uses medical data, personal health history, and known miscarriage risk factors to estimate an individual’s likelihood of experiencing pregnancy loss. The aim is not to replace clinical advice but to enhance early pregnancy care by identifying women and pregnant people who may benefit from additional monitoring or specialist support.
Developed by leading researchers at the Tommy’s National Centre for Miscarriage Research, the calculator uses UK-specific miscarriage data and evidence from extensive clinical studies to ensure accuracy and reliability.
How the Miscarriage Risk Calculator Works
The tool works by asking users to provide detailed but straightforward information about their health and pregnancy history. This may include:
- Age and body mass index (BMI)
- Number of previous pregnancies and miscarriages
- History of preterm birth or stillbirth
- Pre-existing health conditions, such as diabetes or thyroid disorders
- Lifestyle factors, including smoking and alcohol use
- Early pregnancy symptoms and concerns
Once this information is entered, the calculator uses a statistical model based on UK miscarriage research to provide a personalised risk score. It then offers tailored miscarriage prevention advice, signposting users to relevant Tommy’s pregnancy support services or their local NHS care teams.
Why Tommy’s Created This Miscarriage Support Tool
The development of this miscarriage risk assessment tool comes in response to long-standing gaps in early pregnancy care in the UK. Many women and pregnant people only receive specialist support after experiencing three consecutive miscarriages, despite evidence that earlier intervention could prevent further losses.
By launching the Tommy’s miscarriage risk calculator, the charity hopes to:
- Identify high-risk pregnancies sooner
- Provide accessible, evidence-based advice
- Empower pregnant people with knowledge about their health
- Reduce the emotional and physical toll of miscarriage
- Influence policy and encourage earlier NHS intervention
Understanding Miscarriage Risk Factors in the UK
Miscarriage can occur for many reasons, and while some factors are unavoidable, others can be managed with the right care. Common miscarriage risk factors UK include:
- Maternal Age – Risk increases after age 35 and more significantly after age 40.
- Previous Miscarriages – Each past miscarriage slightly increases the likelihood of another.
- Chronic Health Conditions – Conditions like PCOS, lupus, diabetes, and thyroid issues can affect pregnancy.
- Lifestyle Factors – Smoking, high alcohol intake, poor nutrition, and high stress levels may contribute.
- Uterine or Cervical Issues – Structural problems in the womb can increase the risk.
- Genetic Factors – Some miscarriages are linked to chromosomal abnormalities.
The Tommy’s miscarriage risk calculator helps assess how these factors interact, giving a clearer picture of overall risk.

Addressing Concerns About Risk Calculators
Some people may worry that a miscarriage risk calculator could cause unnecessary anxiety. Tommy’s has addressed this by ensuring the tool provides balanced, supportive information alongside risk scores. The focus is not on creating fear but on enabling informed choices and access to care.
Users are also reminded that the tool is not a diagnosis — it’s a guide to help identify whether extra monitoring or specialist care may be beneficial.
Real-Life Impact: Stories from the Community
Many people who have used Tommy’s services have reported feeling more confident and reassured about their pregnancies. For example:
- Sophie, 34, from Manchester – After two miscarriages, Sophie used the calculator early in her next pregnancy. Her results prompted her GP to refer her to a specialist clinic, where she received treatment that helped her carry to term.
- Leanne, 29, from London – As a first-time mum with PCOS, Leanne wanted to understand her risks. The calculator connected her to Tommy’s online resources, giving her dietary and lifestyle tips that improved her confidence.
The Future of Miscarriage Prevention and Guidance in the UK
Tommy’s hopes the success of the miscarriage risk calculator will encourage broader adoption of personalised early pregnancy care within the NHS. By identifying high-risk individuals sooner, healthcare systems can reduce the rate of recurrent miscarriage and improve maternal mental health outcomes.
