my labor crept up on me (it was my first time) and when i tried to sleep, i just couldn't. i woke up at 11 p.m. in increasing labor pains. however i didn't get bloody show until about 5 a.m., the water broke at 6 a.m. and baby was born at 7:42 a.m. so, depending upon your pain threshold, you could be further along than you realize, and it could go faster than you think.
