Lost my mucus plug, and I had contractions that didn't hurt but didn't go away every ten minutes the day before I started getting actual painful contractions. Then the contractions just got more painful until the next night I went into labor and delivery and had my baby 4 hours later. The contractions we're so bad they were making me cry and I couldn't talk or walk through them and that's how I knew it was time to go, plus they were every couple minutes and lasted longer than 30 seconds each.
