Hey Xena,
Go for it re. stretch & sweep - I had two - one last Tuesday when they told me I was 1-1.5cm dilated, which really cheered me up, then one last Friday at 7 days over when I was 2cm dilated and my cervix was effacing nicely - news which really cheered me up again.
Looking back, I think the one on the Friday did the trick - she was really rough and apologised (but it didn't hurt) but my baby was still only 4/5 engaged so she had to reach right up. I think I went into slow labour on the Friday night and all through the Saturday - I had the odd mild dull pain particularly when on long walks and bouncing on my ball and I had lots and lots of clear jelly show on the Saturday. My beautiful baby girl was born on Sunday morning after labouring through the night.
So - go for it! Get the baby out - you must be so uncomfortable. I've been there and sympathise so much hon.
Good luck!
