Abdominal pain in ectopic pregnancy can occur along with menopause, and the typical tearing pain in one side of the lower abdomen after the rupture of an ectopic pregnancy usually occurs between 6 and 8 weeks of pregnancy. The degree of abdominal pain varies with ectopic pregnancy, the rupture of the ectopic pregnancy sac, the location of the ruptured ectopic pregnancy sac, and the individual’s tolerance for pain, which can be accompanied by vague pain in one side of the lower abdomen from the time of delayed menstruation, but the obvious severe tearing pain is unbearable and occurs mostly in the sixth to eighth week of pregnancy. The rupture of ectopic pregnancy is most common with the rupture of fallopian tube pregnancy. The angular pregnancy and cervical pregnancy can tolerate the enlargement of the embryonic sac of pregnancy due to the rich blood supply and good elasticity of the muscle fibers in the location of the gestational sac, and the abdominal pain can occur for a longer time or even without abdominal pain symptoms. After confirmation of pregnancy, it is not possible to judge ectopic and intrauterine pregnancy only by vaginal bleeding, abdominal pain and the rise of blood HCG, etc. A gynecological ultrasound is needed to make a clear judgment.
