The presence of cervical mucus is not a sign that the fetus is in the pelvis. Cervical mucus is a fluid secreted by the mucus glands in the cervical area, and the cervical mucus plug that forms after pregnancy has a protective effect on the pregnancy process. It can prevent infectious diseases in the uterine cavity and also prevent the entry of sperm during intercourse during pregnancy. Dislodgement of the cervical mucus plug is usually caused by a slight widening of the cervical opening during the shortening of the cervical canal and occurs 3-5 days before labor. This may be followed by redness in the vagina and abdominal pain, but does not indicate fetal insertion. The clinical symptoms that indicate fetal delivery include a feeling of the need to urinate and a marked increase in the frequency of urination. The symptoms of upper abdominal fullness are significantly relieved, and some pregnant women experience a feeling of anal swelling, and they always want to relieve themselves but cannot do so.
