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.
The mucus plug accumulates at the cervix during pregnancy. When the cervix begins to open wider, the mucus is discharged into the vagina and may be clear, pink, or slightly bloody. Labor may begin soon after the mucus plug is discharged or one to two weeks later. During contractions, the abdomen becomes hard.
