Can the mucus plug be expelled in the 38th week of pregnancy?

By Silvia Azaña Gutiérrez B.Sc., M.Sc. (embryologist).

Yes, it would be possible. The mucus plug is a mucous-like secretion found in the cervix (cervix) and serves as a barrier to prevent the passage of microorganisms from the vagina into the uterus during pregnancy.

Its expulsion means that the time of delivery is near, but this does not mean that it is imminent and it may take days or even weeks.
