waters have gone but no contractions!!

Amy

my waters went at 9:30pm on the 4th June at 36+6 , confirmed via ultrasound at the hospital yesterday. The dr was happy that baby is absolutley fine and said i could have until 9pm tonight before going back to hospital (currently 4pm in the UK). I was hoping in that time i would have started contractions...but nothing. Been for a walk and on my ball. Any tips? Either way, our baby will be here by the end of the week!
