It doesn't happen for everyone but I lost mine then 30 min later my water broke then I started having contractions but I was also in labor for 24 hours so it all depends on if baby is ready to come out
I lost mine in the middle of the night while in the shower got to the hospital about 8:30-9 had my baby by 4pm. I didn't have any contractions and when I got to the hospital I was already at 7cm
