Uhg... Why won't you poop??!?!?

[Daybreaker]

Thoughts? Am I just worrying about nothing?

I wouldn't worry about it.

Just wondering if it normal for them to go weeks without going, and look rather fat.

Yep, that's normal. Some will get "sausage butt" too right before they go (their back half will look really big and swollen like a sausage).
