Def agree with the pad, if you are leaking even slightly when walking around it may be that they have gone.
Mine went with my third and I wasn't sure but had woke feeling a twang like an elastic bang feeling in the early hours, but thought I had imagined it so went to the toilet and got back in bed. When i woke in the morning I noticed my bump had changed shape and dropped which then made me wonder if my waters had gone,but then nothing else happened.
It was only the next morning that I leaked some more that I then had to put on a pad and they leaked pretty much throughout the day, each time I walked or moved, I went through tons of pads. By this time the midwife had called around (planned HB) and confirmed they had gone, but babies head was preventing a tidal wave!
I had no contractions at all, and would say that if you think there may be a possibilty that I would get checked out,as I am sure you have been advised about risk of infection etc after 24-48 hours of waters breaking.
From what I can recall (sorry if TMI) mine looked a very pale straw like colour and had no real smell,maybe a little musty but def no odour. Whcih makes me wonder if they have gone,best to put your mind at ease.
And I had no control over the gushes coming out,HTH, good luck!
