This maybe a TMI question but how many days before going in to labour did your body/bowels decide to have a 'clear out'?
The last 3 days I've had to run to the loo at least 6 or 7 times and even then nearly been caught short. I have IBS anyway but I've not eaten anything that normally triggers it so I'm not sure whether it's my body preparing for labour or just my bowels playing up.
I'm 39 weeks tomorrow!
