So this will be my third child, I went into labor at 37 weeks with both of my boys. I never lost my plug or had my water break with either one. I'm wondering if this time will be any different. I'm scared I'm just randomly going to go into labor again. My last birth was only 4 hours from start to finish. Any other mommies not get any signs before labor hit?
