My mucus plug came out the day before I went into labor, and since I was way overdue...when I saw the dr. that day I did tell her that I felt the baby was moving a little less. My water broke the next morning and I started having contractions every seven mins. right away.
Re: Do you have to lose your mucus plug first?
My mp didn't come out until I was in labor. Also, didn't notice any change in movement before labor.
