I've done two stretch and sweeps with this pregnancy now. The first one, at 40w6d was no problem. A bit uncomfy during, but no problems afterwards. But when I had the second at 41w1d...Oh god.

I was hurting for 36 hours afterwards. Ow, ow, ow. And I'm still pregnant at 41w4d.
I don't think I'll do it again this pregnancy, although I might in a future one. I have an induction scheduled on Thursday night at 42w. I at least plan to try it for a while, although I may check out AMA if it doesn't do anything. Hopefully my little girl will stop procrastinating before then, though!
ETA: I asked for the stretch and sweep because I considered it the "lesser evil" to a chemical induction. I'm just not sure if it was. Experiences obviously vary even in the same pregnancy. I think if you're facing a deadline it becomes a big question. If you have lots of time left, though...I would wait.
