For me my waterbag burst one night at 3am+ when I was trying to sleep in my bed. Heard a 'gok' sound and thought what it was LOL. After a feel seconds I got up wanting to go pee and felt wet below. Went toilet and saw pinkish water on my panty liner. No contractions though.
Quickly took a shower, check my hospital bag and woke hubby up. Drove me to hospital and was 2cm dilated. Was until about 6am+ then I felt the horrible contractions. My boy was born at 11.35am that morning via natural birth w/o epidural. Considered fast for first birth haha! :-)
