Cervical pregnancy is a relatively rare ectopic pregnancy and a serious disease that is easily missed in clinical diagnosis. It is more common in multiparous women. There are amenorrhea and early pregnancy reactions. The main symptoms are vaginal bleeding or bloody discharge. The amount of bleeding usually increases from a little to a lot, and it can also be intermittent vaginal bleeding. The main signs are significant enlargement of the cervix, softening and turning blue, the edge of the external cervical opening is very thin, the internal opening is tightly closed, and the size and hardness of the uterine body are normal. The embryo of cervical pregnancy implants in the cervical mucosa of the cervical canal, and grows and develops there. Because of its bleeding and the dilation of the cervical opening, it is often mistaken for miscarriage.
