Hi OP, good luck for tomorrow. I am a consultant obstetrician and would agree with a lot of the good advice given out above, esp. speaking to reg or consultant on-call if possible, take in nice food and drink and dvd/mp3 player, books etc, keeping mobile, keep open mind re pain relief.
Induction procedres vary from unit to unit, so make sure you are informed what's the normal process and options at each stage. Contrary to popular belief, we doctors do like people to ask questions and engage with us, and we LOVE it when women have normal deliveries. That's our aim as well as yours, as long as it's safe.
Induction is often straightforward, but there is no avoiding the fact that with an induction versus spontaneous labour, you are more likely for it either to fail to get you into labour, for labour to stop progressing at some point, or for fetal distress. These things all happen in spont labours, yes, but less so. All of these things happen more with first babies too, so if this is your second then problems much less likely.
It's difficult to accept that we have no control over labour to some extent but it's true. I certainly found this difficult as a patient when pg with dd (dc1) - my waters went at T+8 and did not labour after 3 days so was induced. I had the hormone drip and was determined to avoid an epidural at all costs. However once the contractions really kicked in I really needed one and was very grateful for the fantastic pain relief. I ended up with a ventouse for fetal distress but both of us fine.
Contrast that with our second baby (ds) who was also overdue but arrived so quickly we only just got to hospital in time!
Hope all goes well for you and dh and your baby - let us know.
