Ectopic pregnancy and miscarriage: diagnosis and initial management - National Institute for Health and Care Excellence (NICE)
This guideline covers diagnosing and managing ectopic pregnancy and miscarriage in women with complications, such as pain and bleeding, in early pregnancy (that is, up to 13 completed weeks of pregnancy). It aims to improve how early pregnancy loss is diagnosed, and the support women are given, to limit the psychological impact of their loss.
In this guideline, we use the terms 'woman' and 'women', based on the evidence used in its development. The recommendations will also apply to people who do not identify as women but are pregnant or have given birth.
In November 2021, we reviewed the evidence and made new recommendations on the use of progesterone in threatened miscarriage.
