Monitor the movements of the baby, or go in to check yourself. They can tell you if you dilate or so

@sicmermaid, exactly with my son I was losing my mucus plug over the course of weeks and I finally went into labor at 39w5d. I started losing my plug at 35wks. So it just depends on the person

All bodies are different. My first pregnancy, i lost the mucus plug and the next day, water broke and went into labor. No contractions.

2nd pregnancy, plug was out and then next day, had the contractions and went into labor. Some women, it takes weeks after losing the plug.
