Thanks all, just called my midwife. She said its highly unlikely that its a leak of my waters but to keep a pad on and monitor. She'll chat to me in a few hours to see what's happening and maybe pop round and check on the baby too. We're planning on birthing at home. She said if anything makes us more concerned we'll head off the the hospital to see what they say.

I have MASSES of CM whole way through pregnancy, and it gets worse around the time AF should have shown up everymonth...had it last time and so far, this pg is the same.
Lime, what consistency was it do you mind me asking? This stuff I've got going on it quite wet and thin. I'm used the the thick stuff, get that all the time in copious amounts too, but this has just thrown me because its so much thinner. I can't pick up a distinct smell on the pad either so I'm a bit lost there.
