Cervical cerclage is performed because of the laxity of the cervix. If this is the reason for the cerclage in the first pregnancy, it is important to check the cervical cerclage during the preparation for the second pregnancy. If the cervix is loose, it is recommended that the procedure be performed in mid-pregnancy to avoid miscarriage or preterm labor. There are certain risks involved in the procedure, which may lead to miscarriage, preterm labor, hemorrhage, and premature water breakage. It is necessary to take proper rest, avoid sexual intercourse, take absolute bed rest, and apply medications to protect the fetus. Personally, I suggest that it is best to do the circumcision surgery for the second child as well.
