Debbie it sounds just like my labour, stop start, pain mostly in the back and knackered after no sleep. Mine went on like that for 3 days before master made an appearance on the 4th day!! The best piece of advice i can give you is dont fight the contractions, my midwife said thats why it probably took me so long to dilate as every time one came i tensed up and didnt breath through it!! Also try and stay at home as long as possible, dont waste too much energy bouncing on a ball, its important to relax and try and rest even if you cant sleep. The hard bit to come will need all the energy you can muster.
hope it all goes quickly for you, its worth every single second of pain when they put that baby in your arms just remember that when a contraction starts.
