Ectopic pregnancy
A pregnancy where the embryo attaches outside of the uterus. In up to 98% of cases, this will be in a fallopian tube (NICE, 2018). These pregnancies are not viable, as the fallopian tube, or other extrauterine place of attachment, is unable to provide the foetus with nutrients and oxygen via the placenta and is also unable to expand to accommodate them as they grow.
