I just got back too.
Apparently I'm already 2-3 cms dilated, my midwife said it would have been really easy for her to break my waters!!
I'm getting loads of braxtons since I had it aswell, and just hope it means I'm getting somewhere.
I'm booked in for induction on the 8th, when I'll be 10 days over. The good news is that even if I get as far as being induced (my midwife says I won't) I won't need the pessary as my cervix is already ripe, they would just need to break my waters so my labour would be shorter than last time (which was 24 hours)
As far as the actual sweep... I was amazed how "easy" it was It didn't hurt at all, I was expecting major discomfort but it was fine. I know this is probably because I was so soft/dilated, but phew... I was expecting pain!
