I lost mine at 2.30am ish and went into labour within about 6 hours i was 6 days over due tho.
Good luck :)
I lost mine about 24 hours before labour started.. but everyone is different.
Good luck
With my last pregnancy, it went about 8 hours before my water broke. A friend of mine went a week after and that's about the longest I've heard of. It means that s/he will be coming soon!
