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.
When this happens, the mucous plug is no longer large enough to fill the opening and it eventually comes out. It may come out all at once, or it may come out slowly in the vaginal discharge over a couple of days. Losing the mucous plug is a sign your body is starting to prepare for labor. You may lose your plug as early as one to two weeks before the true signs of labor appear, or just as labor itself is beginning.
