In the initial stages of pregnancy, the cervix will begin to thicken and
produce more glandular cells. These glandular cells will release mucus
into the area, which essentially forms a plug that will keep the uterus
closed as the fetus grows.

In women who have never had children, the plug needed is very small; typically,
their cervical openings are minute, often the size of a pinhead. In women
who have had previous pregnancies, their openings are likely to be a bit
larger, so the mucus plug will need to be larger.

During the course of the pregnancy, blood flow will increase to the cervix
and uterus in order to support the womb and fetus. Additionally, hormonal
changes will help the cervix to shorten and open slightly in preparation
for delivery.

When the woman nears the end of her pregnancy, the cervix walls will begin
to thin out (efface) and widen (dilate), eventually causing the mucus
plug to fall out. This will allow the baby to pass through the uterus
and out of the birth canal. The process of effacing and dilating could
happen weeks before delivery begins or it could begin the day the woman
gives birth.

As labor commences, the cervix will respond to uterine pressure and contractions
until the baby has been successfully delivered.
