In brief: Minimal concern
Mucinex (guaifenesin) is guiafenesin, an expectorant-- a medicine to thin mucus so that it can more easily be cleared from the throat and sinuses.
It is a pregnancy category c drug, so should be used with caution. There is no mucus is the womb to speak of, and there is no evidence that the presence or absence of cervical mucus has significance to fetal well-being.
