No way to learn but by asking questions!

BH generally gradually die out if you change your activities - ie. if they are happening at rest, a walk will make them stop, and if they are happening when you are active, resting, or having a warm bath will stop them. Just a rule of thumb, not a guarantee.

As far as water breaking goes, there was just a poll done recently here on BB, I think in the labour and delivery section, on water breaking. It can happen well before labour starts (then you might have to be induced) or a little while before labour, or in early labour, or in hard labour, or during pushing, or not at all. Very rarely, a baby is born with waters intact. Usually they break at some point during labour, whether naturally or with the OB or midwife breaking them to help things along.
