A cervical mucus plug is a type of mucus secreted by the cells of the cervical canal that can act like a cork to plug the cervical canal and protect the uterine cavity. The flow of cervical mucus plug in late pregnancy indicates that the inner cervical opening has become soft, and has no particular relation to how soon the baby will be born, nor is it a premonition before labor. If a pregnant woman experiences irregular contractions, a feeling of the fetus descending, or seeing red in late pregnancy, this is an omen that she is about to give birth. Once regular contractions, dilatation of the mouth of the uterus and other symptoms of impending labor occur, it is necessary to be hospitalized in time to wait for delivery. The cervical mucus pessary has no relation to whether or not you are in labor. In late pregnancy, if the pregnant woman is healthy, she can go outdoors appropriately, which will help the labor. However, the activities should be based on their own conditions, and it is best to be accompanied by family members. Pregnant women should also pay attention to the fetal heart and fetal movement, if there is any abnormality, timely medical examination.
