I'm in the camp that says nothing will 'work' unless you were about to go into labor anyways. So feel free to try all those things. If they work, then you were going to go into labor anyways. If they don't, then you weren't.
I mean, check out the April mommas. We got a momma who's been at a 7 for weeks, but not in active labor. I, on the other hand, have gone into labor spontaneously at a zero/closed with two babies. Dilation just simply doesn't tell you anything. That's why some doctors don't do checks anymore - because they're pointless and really don't mean anything.
But, I hope that your baby is able to come naturally and I hope that your baby isn't 11 lbs and cause you additional damage. Best of luck!
