I forgot to add, yes you can walk around with the syntocin drip. And you can have it turned off, up the dosage etc as you go.
I had a stretch and sweep done a few days before I went into labour. Have you considered this? Also me and dh dtd and went into labour an hour afterwards, so I think these 2 things helped me get into labour spontaneously.
Because in labour the whole thing can be a blur etc I found it really good that my dh knew what my wishes were for the birth. Obviously not everyone gets their birth to plan etc. my birth plan was not referred to once, preferred to see how I felt as I went along.
Good luck! 2 days ain't long!
