Why do we need this research?
As many as one in four women will experience a miscarriage in their lifetime. 1% of women will suffer three or more miscarriages. We still don’t know enough about miscarriage to be able to give women the reason why it happened to them, or to predict the chances of it happening again in the future.
We need better tests to accurately predict the likelihood that a woman will have a miscarriage, whether they’ve had one in the past or not.
What’s happening in this project?
To understand miscarriage better and find ways to predict it, Tommy’s are supporting The Early Pregnancy Observational Study (EPOS). This study is following more than 1,100 women from five weeks of pregnancy through to birth.
Our researchers take samples of blood, urine, and swabs from the vagina to look for substances or bacteria that could help us understand why miscarriage happens. The team also carry out an ultrasound scan of the baby, and collect information about the women’s clinical history. Women will have follow-up visits every two weeks in the first trimester, and one check-up in the second and third trimesters.
Early results have shown that there are significant differences in the amount of two substances in the blood of women who miscarry, compared to women who have a normal pregnancy.
The research team have also revealed how in women who have been pregnant more than once, the bacteria present in her vagina changes. Tommy’s researchers are studying how the bacteria present in the vagina might influence the chances of miscarriage, so knowing how bacteria naturally changes between pregnancies is vital information.
EPOS is also connected to other trials supported by Tommy’s:
- The PRECISE study – How to spot heart problems earlier in pregnancy
- The ABPEP study – Finding ectopic pregnancies early in pregnancy
What difference will this project make?
Our researchers believe that the results from EPOS will help us to understand why miscarriage happens, to detect problems earlier in pregnancy, and to work towards treatments to prevent miscarriage.

A recently published article, co-authored by Professor Catherine Williamson from Tommy’s Research Centre at King’s College London, suggests that certain pregnancy complications can indicate future health issues for women.
Tommy’s has received a grant from the UK Government’s Department for Health and Social Care to support the costs of its PregnancyHub information and support services throughout the summer, due to rising demand in the wake of coronavirus.
Although recruitment to some clinical trials had to be paused when coronavirus hit the UK, scientists at Tommy’s Research Centres across the UK are still hard at work, supporting women and families in our specialist clinics and sharing their latest studies with academic journals.
The day before Mother’s Day, and two days before the UK officially went into coronavirus lockdown, Zara Dawson found out she was having a miscarriage. Her third consecutive miscarriage in less than a year, and fourth consecutive loss, after losing her second son Jesse in 2018 to termination for medical reasons.
