The main manifestations are preterm labor and repeated miscarriages in the middle and late stages of pregnancy. Cervical insufficiency cannot be cured on its own. Cervical insufficiency detected during pregnancy should be treated with cervical cerclage in time to avoid adverse effects on oneself and the fetus.

At the same time, keep a good mood, rest more, ensure regular work and rest, should not be overworked.
