Critical Period: Embryology As is well known, a certain organ arises much earlier or later in the embryo than certain others.
How soon after my mucus plug passes will labor begin? Passing a mucus plug is a sign that your cervix is dilating and that your body is preparing for birth. Labor could be hours, days, or even weeks away as the cervix gradually opens. The mucus plug is usually clear, slightly pink or blood tinged in color. It can be stringy mucus or a sticky discharge.
As your cervix prepares for labour, the mucus plug is released. It can come out all at once, or in small amounts. You may notice a heavy discharge, or a discharge streaked with blood in your underwear or when you go to the toilet.
