Best of luck to you. I had a S &S done on the tuesday at 1pm. I was 1-2 cm dilated and bubs was engaged and good to go - just like you. Had the same sort of bloody mucous also. My pre labour started at 9pm wednesday and full labout at 12:30pm on the thursday so pretty much 48 hours from the S&S to established labour. My waters broke by themselves a few hours later.
