The mucus plug often looks like a jelly-like chunk of discharge that is clear, slightly pink, or tinged with a small amount of blood. Sometimes, instead of a jelly-like chunk, in some women the mucus plug looks like stringy mucus or a sticky discharge.
While blood in the mucus plug can be normal, the amount of blood is generally a spot -- no more than a teaspoon or two. If you have more blood than that, contact your healthcare provider.
What Is the Purpose of the Mucus Plug?
During pregnancy, the mucus plug acts as a barrier at the entrance of the cervix. It seals the cervix and prevents bacteria from entering the uterus.
Remember, the mucus plug only seals the cervix -- so losing your mucus plug does not mean the amniotic sac is open to infection. The amniotic sac is still sealed until your water breaks.
