Yeah i agree, lots of walking or jump up and down. Sex is meant to bring it on also but from experience it never worked for me and that was one of the last things i felt like doing especially at 39 weeks.
Good luck
I would walk, walk, and do more walking! lol. And have lots of sex! I also got on my exercise ball and bounced up and down on it... my midwife said that could help things along. You are getting there! =)
It could mean that baby is on their way. The problem is that you can be dilated and effaced for days, even weeks. I know, I'm not helping. But there really isn't any good indication that labor is coming unless your water breaks or you're having intense contractions.
