I had pre-labour on and off for a few weeks each time. But nothing in the two days leading up to the birth. When I went into labour finally, the first was 1hr 50minutes from first contraction to baby. Second was 5ominutes from first contraction to baby and third was my longest(!!!!!!) at 2 hours from first contraction to baby. The third time I actually slowed down her labour by laying down and not being active so the midwife would make it. It was hard but worth it!
Just be ready for a quick labour if it doesn't happen at least you were ready! Towels and blankets in the car!!!
