Soph, have you been using anything like Evening Primrose Oil capsules?? These really do help to soften up your cervix. If your waters haven't broken or anything then you would still be right to use them. Can't hurt hey??

Maybe you could've asked for a stretch and sweep when you were there.

But generally they say 1cm for each hour, although quite often that's not the case. Especially for your 2nd or subseqent babies.
