It doesn't nescessarily have to be the runs. Just going a lot to clear out the system.

That being said I sometimes have this happen and it freaks me out as i am paraniod about preterm labour due to my first early bub. Especialy when the baby is also having a quiet day.

So it's one of those sometimes it does and sometimes it doesn't. I can't actually remember what my bowel movements were like just before i went into labour as unlike you i wasn't near my due date so the anticiapation wasn't there.

The only thing i remember was telling my mum it felt like i was getting my period (so possibily runs as i usually get 'runs' right before and during the first day or so of my period). Of course at the time she laughed and said that was highly unlikely since i was 8mths preg. But i was right, i got my 'period' two days later.
