I had my baby june 8th. On my due date. I had sooo many signs of labor up until like 38-39 wks. So i wouldn't worry about that. I literally wasn't having braxton hicks, baby didn't drop, and i didn't have my bloody show or anything and at 11pm i started contracting, started to time them around midnight due to them being frequent and than went to the hospital. Your baby will come when its ready. Having no signs is nothing to worry about.
Same here. 38 weeks +, only dilated to 1.5cm for the last two weeks. Really don't want a c-section either.
