i had obs trying to tell me 'theyve seen so many women like me' and i probably woudlnt go into labour for two days as my cervix was long and close, and they were pushing me for induction, but i stood my ground and went into labour within about 4hrs of that battle with them (I just had faith that all would be well and it was) and I was a bit of a shock for the Dr's as I didnt fit their 'textbook' picture, so it CAN change dramatically and very quickly. i also had obs tell me that other women have ended up with a hysterectomy because their labours have gone on too long.. but i chose to go with my instinct which said everything would be fine.
