The appearance of cervical mucus in late pregnancy is mostly indicative of the imminent start of labor and is as specific as the onset of redness and the regular contractions of the uterus. Cervical mucus, also known as mucus plug, is a colorless, yellowish substance similar to leukorrhea that is secreted by the mucous membrane of the cervical canal after a woman’s pregnancy. It blocks the cervical canal, thus isolating the uterine cavity from the vagina and preventing the upward invasion of bacterial microorganisms from the vagina, and acting as a self-protection. During late pregnancy, the cervix is stimulated by hormones in the body and gradually shortens and grows flat, so the mucus that stays at the endocervix will be discharged from the endocervix. If a cervical mucus plug is found to be discharged, it means that the opening of the cervix begins to dilate and labor can often occur within 3-5 days, which may be accompanied by false contractions, a feeling of fetal descent, and redness. Women with cervical mucus in late pregnancy should pay attention to local cleanliness and hygiene, often washing the vulva with water, avoiding sitz baths and tub baths, and choosing showers. Change your underwear regularly, and it is best to wear breathable cotton underwear. Avoid strenuous exercise and ensure sufficient sleep. Try to eat less and more often and eat lightly. If necessary, prepare the necessary items for delivery to go to the hospital for delivery and closely monitor the fetal heart changes.
