Ectopic pregnancy means that the fertilized egg does not settle in the uterine cavity, but elsewhere outside the uterine body. After intercourse, the sperm will travel from the woman’s vagina to the uterine cavity and enter the fallopian tube, so it will unite with the egg in the fallopian tube to form a fertilized egg. After the union, the fertilized egg will increase in size, and with the peristaltic movement of the fallopian tube, it will slowly travel to the uterine cavity for implantation, thus causing the embryo to grow and develop in the uterine cavity. However, if the fallopian tubes are not open, then the fertilized egg will increase in size, so it may be laid directly in the fallopian tubes and will not be able to travel to the uterine cavity for implantation, resulting in ectopic pregnancy. Because of the poor growth environment outside the uterine cavity and the relatively small size of the fallopian tube, the embryo in the tubal bureau may experience abnormal bleeding as the time of menopause increases, and may also cause severe pain in the lower abdomen due to the rupture of the mass, and may even cause hemorrhagic shock. Ectopic pregnancy is a particularly dangerous disease that should be treated promptly once it is detected. Women who do not receive active treatment leading to rupture of the mass and abdominal hemorrhage may often endanger their lives due to untimely resuscitation. Therefore, if a woman experiences abnormal bleeding and abdominal pain when her menstrual cycle is pushed back, she must go to a hospital gynecological examination as soon as possible to determine if the pregnancy is intrauterine.
