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.
This causes the mucus plug that has sealed the entrance to your womb (uterus) during your pregnancy to slip away. Your labour may not start for hours or even days after you lose the mucus plug. Or you could already be in early labour. Early labour, when your cervix starts to open, is when you may feel mild contractions, tummy aches, cramps or backache. When the mucus plug dislodges from your cervix it's called the show, or a bloody show. The jelly-like plug is often blood-tinged or streaked with old, brownish blood when it comes away.
