Crampy... Does it mean anything?

Aisha
I'm due tomorrow and for the past few days I've been a little crampy down there. Nothing major just like light period cramps. 
Could it mean labour is close or is it possible that it will still take another week...? 
It's a weird feeling as well to feel baby's head (and fists?) squirming all the way down behind my pubic bone 😳 She's really got her head pretty deep in my pelvis now... And her movement doesn't seem to be slowing down at all.
