How is habitual abortion staged?

There are four types of habitual abortion: early primary, secondary, late primary, and secondary. Late abortion is mainly caused by cervical problems, while early abortion is mainly caused by maternal and paternal factors, the embryo itself, and uterine factors. Treatment is based on the cause.

Habitual abortion includes early primary, which is the first pregnancy, with two spontaneous abortions within 12 weeks of amenorrhea. Early secondary, which is a normal pregnancy before, with two spontaneous abortions within 12 weeks of amenorrhea. Late primary, which is a first pregnancy with two spontaneous abortions between 12 and 28 weeks, and late secondary, which is a normal pregnancy before, with two spontaneous abortions between 12 and 28 weeks of amenorrhea.
It is recommended that when habitual miscarriage is discovered, the cause should be determined based on the stage, and early examination and treatment measures should be taken.
