Thats not entirely true Tastic - I had a stretch & sweep 2 days before going into labour - My MW stretched me to 3cms and told me if I or DH felt curious we could feel babys head

Not that I did (well bit hard to actually reach

) and DH was a little repulsed by the very thought lol!
I say go for it - granted you have clean hands of course
ETA - sorry didn't read your OP properly - I'm not sure what the cervix is supposed to feel like I'm afraid, like I said I never ventured down there. You could try googling? Either way, you're not too far off meeting your wee one - best of luck
