I don't know how to move your cervix - Mine wasn't in the right place with DD1 & the ob 'pulled' it down under her head. Owww!

But if you wanna help to get labour going on your own, I reckon get walking.

DD1 - 7 days over due, Went shopping in Coffs for the day with IL's. Waters broke at 12.30 that night. Was born at 6pm the next night. Had done alot of walking through the pg too.

DD2 - 7 days over due, Contractions started at 2.15am & stayed 15 minutes apart all day. At 3 or 4 in the afternoon I decided to go for a walk. DH & I walked about 5 k's slowly. 10.30 that night it all got full on & she was born at 7 the next morning. Had done alot of walking in that pg too.

DS - walked about 2 kms. Was born at 10.15 next morning.

I don't recommend walking for k's like I did. I only did that coz I walked every night through my pgs. About a k a night. I was pretty fit, so I was able to do it.
Just go for a walk whenever you can. It might help. Well it worked for me.
