Ectopic pregnancy refers to the implantation of the fertilized egg outside the uterine cavity. Because it is not in the environment of the uterus, ectopic pregnancies often end in miscarriage or rupture. The symptoms of an ectopic pregnancy mainly depend on the location of the implantation of the fertilized egg, whether a miscarriage or rupture has occurred, the amount of bleeding, the duration of the bleeding, and whether there is a rupture or miscarriage in a tubal pregnancy. Generally, there are often no specific clinical manifestations in the early stages. If it reaches the middle to late stages, there might be symptoms such as abdominal pain and vaginal bleeding. If a tubal pregnancy ruptures, the abdominal pain follows a series of tearing pains, then progresses to generalized abdominal tenderness and rebound pain.
