With Jazz I was in spontaneous/natural labour until the hospital and then had to be augmented because my cervix wasn't dilating fast enough for the midwives.

With the drip it was fast and furious, well the contractions were anyway (I was on the drip for 10 hours, and I was already 4cm when they started).

Before then they hurt but it wasn't so fast and unpredictable (the contractions on the drip folowed no rhyme or reason, for me anyway), things pregressed one step at a time. Just not fast enough apparently.

You *may* find (fortunately or unfortunately?) that without the drip things won't go as fast... It more than likely won't start as fast anyway, so you'll have time to realise that its labour and get to the birth centre.
