I'm just curious - not currently pregnant, but when I went into labour I followed the advice in the NHS book and called when contractions were 5mins apart. They pretty much said stay home as long as you can stand it. When you can't, come in. (my waters hadn't broken). I went in several hrs later, only 2-3cm dilated and decided to go home again as still too early for gas & air / epidural. Just an hr or so later, I felt like I needed a big s*t (!) but thought couldn't be baby as had still been in prelabour. waited another couple of hrs then decided just to go back to hospital and promptly had membranes ruptured and told to push as was fully dilated. Big s*t feelings clearly ds trying to get out! It made me wonder whether I left it too long to go back. Would be interested if anyone knows what criteria are used if any other than waters breaking and pain.
