In women, bleeding from ectopic pregnancy will definitely cause abdominal pain, which will be manifested by blood irritation of the peritoneum, and the most common type of ectopic pregnancy, accounting for 95% of cases, is tubal pregnancy. Abdominal pain is the main symptom of ectopic pregnancy. Before the miscarriage and rupture of tubal pregnancy, the embryo gradually increases in size in the fallopian tube, which can manifest as vague pain in one side of the lower abdomen, which is not particularly obvious. The severity of abdominal pain is proportional to the severity of the condition of ectopic pregnancy bleeding and the amount of bleeding. When the bleeding is confined to the lesion area, it mainly manifests as pain in the lower abdomen, and when the blood accumulates in the rectal sink of the uterus, a feeling of anal cramping may occur. With the blood, flowing from the lower abdomen to the whole abdomen, the pain can spread from the lower abdomen to the whole abdomen, and the blood stimulating the diaphragm can also cause radioactive pain in the scapula and chest pain.
