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.

We asked our lovely friend and supporter, Jennie Agg, what motherhood and Mother's Day means to her. In this piece, she speaks of her difficult past experiences of Mother's Day, how she has grappled with a sense of being in limbo, and the ultimate purity of her feeling of mother love.
In the lead up to Mother's Day, you might find yourself thinking about how to process your emotions and what to do on the day itself. The anticipation can often feel scary or daunting, and finding ways to look after yourself is important. In this blog, you'll find advice from a few of our lovely supporters who understand how you're feeling.
