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.
In most cases the mucous plug usually comes out after having a cervical examination and obviously sometimes it just comes out by itself. Either way, this does not give any indication as to when labor may begin.
