The precursors of an ectopic pregnancy can manifest as unilateral lower abdominal dropping pain, and there may be irregular vaginal bleeding. After 50 days of pregnancy, the gestational sac is not visible in the uterine cavity, and the symptoms of an ectopic pregnancy are atypical. Some people may experience severe bleeding and go into shock. In cases of ectopic pregnancy, it is imperative to go to the hospital for an ultrasound to determine the size and location of the gestational sac and confirm whether it is an ectopic pregnancy. Timely hospitalization and treatment are necessary if an ectopic pregnancy is confirmed.
