I waited a whole night in hospital before they even started my induction, be prepared for some waiting around, take stuff to keep you occupied, take a comfy pillow for your other half or birth partner and ask for a reclining chair for them. One curious can be quick or take days, I started on a Tuesday and gave birth on Thursday. If you are given gel my advice would be to try and get your body into labour spirit by walking around, bouncing on ball, I believe these things in the end helped my cervix to dilate and was able to give birth vaginally. If you're not against epidural, have it before they start you on the drip (if it comes to that). Trying to fit an epidural whilst you're having painful contractions is more risky then just having it fitted before they start you off on drip.
Also, listen to your body!! The contraction monitor was not picking up my contractions properly, midwife was looking and saying that my contractions are not demonstrating that I'm anywhere near giving birth yet. To me they hurt like hell, and the epidural wasn't working. In the end I gave up and said switch the drip off, top up my pain relief and I'm done with this because I'm in so much pain and being told I'm not anywhere near giving birth. I gave in to the fact that the next step was a c section.
The drs came and said ok the next step from here is a c section, the dr then examined me and said 'well I can tell you why your epidural hasn't been working!, you're fully dilated!'
They switched the drip back on, I pushed for 40 mins and my DS arrived. Trust your instincts and your body, not machines! Xx
