Can anyone help out?

At about 2.20am this morning, I was half asleep and laying on my side, I feel a pop, and a little bit of liquid leaks out. So off I go to the loo, and there is some on the pad. Still half asleep, I call the hospital up again (they must be sick of me now), and tell them I think my waters have broken. She asks me a whole heap of questions, tells me too keep the pad on, and each time I have a contraction, some liquid should leak out, and to call back in an hour and see how we're going.

I went back to slepp just after three, and after havin a fair few more contractions and although they are more painful than before, no leaking liquid. Which is what the midwife said to call back about.

My question is, every time I stand or walk, it feels like a rounded anvil is on my pelvis - it didn't feel like that before hand. Sitting isn't too bad, and it isn't there at all if I lay down, but I'm wondering if that means that my waters have broken? Cause bub doesn't have anything but my pelvis to rest his head on now?

Please help. I feel like such an idiot calling up the hospital all the time. I know they expect it and every thing, but it doesn't help me feel any less of a moron.
