Okay I'm no expert obviously (I'm still waiting), but from all the pre labour stuff I've read, until your contractions are regular and more painful, it sounds like your body is not in labour yet, so you should have time from when it does start. It sounds like your body is one that just has a lot of pre labour symptoms as opposed to some that don't. It's teasing you!
A friend of mine who had BH for a few days said she really knew the difference when real contractions started as they were so regular and strong.

Also all that wetness etc, it could be a number of things that your body is doing in preparation. I have had that some days where there is a lot of wetness and it's def not urine or waters breaking. It must just be bodily fluids of some knind working their magic!

Anyway if you are really worried you should give the hospital a ring, it is better to be safe than sorry.

Good luck anyway and keep us posted!
