The early symptoms of an ectopic pregnancy, where the pregnancy test shows implantation outside the uterine cavity, indicate an ectopic pregnancy. Depending on the type of ectopic pregnancy, whether there is a miscarriage at the site where the fertilized egg attaches, or whether there is a rupture, as well as the timing, duration, and volume of bleeding, the clinical manifestations can vary. In early tubal pregnancies, if there is no miscarriage or rupture, there are generally no specific clinical symptoms, meaning there is neither abdominal pain nor vaginal bleeding. However, as the condition progresses, some typical symptoms may appear, beginning with the cessation of menstruation. Then, abdominal pain may occur. If there is no rupture, the pain or soreness is typically localized to one side of the lower abdomen. If a rupture occurs, tearing pain will be followed by lower abdominal pain, abdominal tenderness, and rebound pain, potentially leading to a shock state.
