It sounds like you are having a right nightmare Fuffins!!! I would like to have been able to tell you it is all much easier second time around!!!
I don't blame you for not wanting induction - I don't think I would either. I had the same thing with my 1st - was 2 weeks over but still sent home due to lack of staff; then had similar to you, contractions for days and progressed really slowly Went to and from the hospital but 2nd time around I just stayed at home until I was sure serious stuff was happening - went in and they said I was 4cms, and Rose was born 8 hrs later.
Just take it easy and try to relax (know how difficult it is).
All the best, not much longer now,
