I had zip until my waters broke and DD arrived 2 hours later. She was 7 days late. I was having BH but I could barely feel them. I was 2cm dilated on DD's due date when my ob did a S&S. I also had no pre-labour with DS. His labour started with contractions that built up slowly. He was 11 days late. BH with him were a bit more noticeable but not enough to make me wonder if they were "real" contractions IYKWIM.
