All about the Mucus Plug

11 May 2010 No Responses

A cervical mucus plug is a collection of cervical mucus that acts as a plug and seals the cervical canal during a pregnancy. The mucus plug is a protective barrier that keeps bacteria from entering the uterus.

At the start of a pregnancy the cervical mucus is a thick, cloudy or clear colour and sticky in texture.

As the woman gets closer to labor the cervix thins and some blood will mix with the mucus plug, which can give it a brown, pink or reddish tinge. When in labor, as the cervix dilates the mucus plug will dislodge from the uterus and may come out of the vagina as a lump, blotches or as increased vaginal discharge over the course of a few days. Loss of the plug does not strictly imply that delivery is fast approaching.

There are other factors to why the cervical mucus will come out such as a vaginal examination or sexual intercourse will disturb the mucus plug. If you notice any blood tinged mucus before the thirty-sixth week of pregnancy or have a history of preterm labor, it is strongly advised that you consult with your doctor as soon as possible.
