Effacement
Prior to pregnancy and in the first and second trimester, as well as much of the third trimester,
your cervix is long and thick. As labor nears it begins to shorten and
thin out. This action is referred to as effacement. As your cervix
begins to efface, the plug keeping the entrance to the uterus sealed is
released. This is called your mucus plug and it may contain some blood.
Effacement is generally measured in percentages by
doctors and midwives. When you have an exam your provider will tell you
that it is anywhere from 0% to 100% which means not effaced at all to
completely effaced and thin. When it is completely effaced it becomes a
part of the uterine wall, allowing the baby to pass through.From www.babiesonline.com
