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.
However, as the cervix begins to efface and blood is released, there may be some blood deposited onto the mucus plug. As your cervix dilates you will begin to lose the plug, either in bits of stringy, blood tinted mucus over a period of time, or all at once. This can happen up to two weeks before labor actually begins.
