A miscarriage is the loss of a pregnancy during the first 23 weeks. The main sign of a miscarriage is vaginal bleeding. This may be followed by cramping and pain in the lower abdomen.
An ectopic pregnancy is a pregnancy that develops in the fallopian tubes instead of in the womb. Sometimes an ectopic pregnancy can also develop in the abdominal cavity. An ectopic pregnancy is a serious, life-threatening condition and will end in miscarriage.
- As many as 1 in 4 pregnancies end in miscarriage
- Among women who know they are pregnant, it is estimated that 1 in 6 pregnancies end in miscarriage.
- 1 in 4 women experience a miscarriage during their lifetimes
- The majority of miscarriages happen in the first trimester – over 80% of miscarriages occur before 12 weeks (which is why the Tommy’s National Miscarriage Centre’s research is dedicated to exploring the causes of early miscarriage)
- The overall risk of miscarriage under 12 weeks in known pregnancies is 1 in 5
- In women with a BMI over 30, the risk is 1 in 4
- 1 in every 80-90 pregnancies is ectopic, which is around 12,000 pregnancies a year
- About 1 in 100 women in the UK experience recurrent miscarriages.
Research into why miscarriage happens is the only way we can save lives and prevent future loss. In 2016, Tommy’s opened the UK’s first national centre dedicated to miscarriage research.
