The typical symptoms of ectopic pregnancy include menopause, abdominal pain, and vaginal bleeding. There is usually a history of menopause of 6-8 weeks, but interstitial tubal pregnancy has a longer menopause, and there is also a history of no menopause in 20-30% of patients. Abdominal pain is the main symptom in 95% of patients with tubal pregnancy. Prior to miscarriage or rupture of tubal pregnancy, it often presents as vague pain or soreness in one side of the lower abdomen due to the gradual enlargement of the embryo in the fallopian tube. When miscarriage or rupture of tubal pregnancy occurs, there is sudden onset of tearing pain in one side of the lower abdomen, often accompanied by nausea and vomiting. Vaginal bleeding accounts for 60-80% of cases. After the embryo dies, there is often irregular vaginal bleeding that is dark red or dark brown in color. The amount of vaginal bleeding is small and dripping and usually does not exceed the amount of menstruation. In a few patients, the amount of vaginal bleeding is higher and the amount is close to menstruation. The vaginal bleeding may be accompanied by meconium tubular pattern or meconium fragment discharge, which is the result of uterine meconium detachment, and the vaginal bleeding needs to stop only after the lesion is removed.
