Divvy - I have had the same thing in the past week and like you(even though it's a touch early for me) I am hoping that it means that the time is coming closer.
I am wearing panty liners, which arent to bad actually. I find that its almost as though I am sweating lots there too. I smell acidic down there too I have to add.

I hope that it is a sign of your birth coming up soon!
