I am same as you Nat, being told your not ready, but actually feeling that overwhelming urge to push & sneaking a few in before telling them I feel like pushing!!!

Mind you I was told I was only 7 cms & then hopped in a boiling hot bath where I kind of fainted & saw blood in the water so panicked & got out immediately & then started pushing secretly on way back to bed as I just had too, then when I was up on bed I said I need to push & the MW said No your onlt 7cms, I still gave a few pushes & my Mum said 'are you pushing?' I nodded & the midwife looked & there was Maddy's head already!!!!

Definately trust your body, it's the only thing that is telling you whats really going on...
Coz with Indah the trainee said it was my cervix & I was closed, but I knew I was close next nurse looked & said your waters will break any time now & shortly after Whoosh!!!! Luckily I didnt go home!!!

OOOH makes me excited to be at that exciting piunt in preg again... I could skip the 9 months & go straight into labour I actually enjoy it!!!!
