Eat, drink and try to go back to sleep. It could be hours before contractions start properly -was able to take number 1 child to mother and toddlers and spend the day doing things before they started with number 2 child. Number 3 was about three hours between waters going and cx starting. About 6 or 7 with child 1.
Great that contractions are starting. My waters broke (during the European Cup Final, was I popular!) went straight to hospital on the advice of the midwife and then spent a boring night and morning with nothing doing.
Stay at home as long as you feel comfortable doing that and get some rest.
Eeek... not sure if my waters have broken, currently sitting very still and has stopped for now. Taken to wearing a maternity pad (!) and waiting for DH to arrive home and take me to the birth centre for a check-up. Bit worried as no TENS machine (just 37 weeks) and only half packed bags.
Hoping things are moving along for you and you'll meet your baby soon.
