The cervix and the uterus are connected, but there is a difference between the two: the cervix and the vaginal end are connected, while the uterus and the vaginal end are connected through the cervix, and the mucous membrane in the cervix does not undergo cyclic changes, while the mucous membrane in the uterus undergoes cyclic changes, which is clinically referred to as menstruation, under the effect of the ovaries’ cyclic secretion of estrogen and progesterone, which is the main difference between the two. In addition, if the pregnancy is intrauterine, it is a normal pregnancy, which can reach full term and be delivered by cesarean section or vaginal delivery, but cervical pregnancy is ectopic pregnancy, which often leads to massive bleeding, endangering the patient’s life, and must be promptly given to terminate the pregnancy, which is also the main difference between the two.
