Whether cervical cerclage is recommended at 28 weeks of pregnancy needs to be judged on an individual basis and is not always necessary. If cervical insufficiency or cervical laxity occurs at 28 weeks of pregnancy, emergency cervical cerclage may be needed to avoid premature labor. If there is no discomfort during pregnancy, the fetus is developing well, and the pregnant woman is in normal physical condition, cervical cerclage is usually not necessary. If there have been multiple miscarriages, mid-term preterm labor, etc., and the pregnant woman has cervical problems, cervical cerclage can be performed around 12-14 weeks of pregnancy, which can effectively prevent miscarriage or preterm labor. Regular medical checkups are required during pregnancy, and it is best to seek prompt medical attention if there are any abnormalities.
