For what its worth, I am in much the same boat, with random tightenings and menstrual like pains waking me in the middle of the night....the nothing. I too have no sign of my mucus plug, no waters, no nothing!

Yep, its starting to drive me crazy too.

Good advice from Tobily, I try to just keep dismissing it as my body preparing and not get too excited- but that's really hard!!! As Tobily said, I figure when we are in full on labour, we will know it! Im just trying to keep busy till then...

Good luck and hope it all goes well for you! Sending labour vibes.
