I was 90% effaced before my due date. cant remember dilation but nothing more than 2 ,I still didn't go into labor until 4 days later. I was 40w3d when I was 3 cm and 90% effaced. I went into labor that night and was 4cm 100% effaced by the time I got to hospital and my water broke an hour later I was 7cm lol

I was 3cm dilated at 36 weeks. my son stayed in there until his due date but my dr did put me on bed rest the last month just to make sure.
