with my last pregnancy i just had I had no idea i was in labor since i was in preterm labor for weeeks. My water did not even break when my son came out. Came out sack and all. I had my son in our car on the way to the hospital. I had to rip open the sack to pull him out, TMI it was GROSS! Apparently the cramps i had the night before i had him was doing something and i had NO idea. You never know when you are i labor until it happens really.
