Good luck Jacks mummy - I am still jealous!
Tamarra, it can be hours after your waters break before you feel contractions. usually they say if you haven't started contracting within 24 hours of your waters breaking they will induce you.
You will know what contractions feel like when they hot up, to start with you may not know you are having them, but they will get gradually closer together, last longer and be more painful. By the time you are having 3 in 10 minutes they will be pretty painful. Good luck
