What are the symptoms of habitual miscarriage? Pregnant women should take precautions in advance and protect the fetus in time if they are found

Some women cannot give birth to babies every time they get pregnant, and they will have miscarriages every certain month. If a woman has spontaneous miscarriages for 3 or more consecutive times during pregnancy, it is confirmed as habitual miscarriage. In fact, habitual miscarriage has some symptoms. Pregnant women should take precautions in advance and protect the fetus in time once they are discovered. So what are the symptoms of habitual miscarriage?

Habitual abortion refers to three or more consecutive spontaneous abortions. Each abortion often occurs in the same month of pregnancy, and the abortion process is the same as that of general abortion. In recent years, habitual abortion has been called recurrent abortion internationally. In the early stage of habitual abortion, there is a small amount of vaginal bleeding, or slight lower abdominal pain. The bleeding time can last for several days or weeks, and the amount of blood is small. Bed rest and medication are not effective. In the late stage, the amount of vaginal bleeding increases and the abdominal pain worsens. At this time, the cervical opening is checked and it can be found to be dilated, or the fetal sac is seen to be blocked at the cervical opening, which is irreversible.

After the symptoms of habitual abortion appear, if all the products of conception are expelled, it is called complete abortion; if only part of the products of conception are expelled and some remain in the uterine cavity, it is called incomplete abortion and requires immediate uterine curettage. The clinical manifestations of habitual abortion are the same as those of general abortion, and can also go through several stages of threatened abortion, inevitable abortion, incomplete or complete abortion.

According to the timing of habitual abortion, it is divided into early habitual abortion and late habitual abortion. Early habitual abortion refers to abortion before 12 weeks of pregnancy, which is generally related to genetic factors, maternal endocrine disorders and immunological factors; late habitual abortion refers to abortion after 12 weeks of pregnancy, which is often caused by relaxation of the internal cervical os. Or it is mostly due to damage to the cervical os caused by curettage or dilation of the cervix. A few may be related to congenital developmental abnormalities, malformations, blood type incompatibility and maternal diseases. In addition, habitual abortion can be divided into primary and secondary types according to whether there is a normal reproductive history before habitual abortion.
