Firstly, apologies for the TMI... 
I've had diarrhoea for the past 4 days. Not chronic, but it's there all the same.
Is this a definite pre-cursor to labour? Braxton hicks coming and going as usual, pelvic and back low-level pain... nothing too uncomfortable or unusual...
I've been having "engagement pains" low down in my abdomen, which are getting more intense as the days go by.
Has anyone else had this and not gone into labour shortly after?
