the first thing to do is take a deep breath. it's good to worry because it shows you care, but you seemed totally worked into a tizzy. if you have things set up correctly, the snake will know what temps it wants to be at. mine never move... ever... well the male does, but the only time i see the female is when i feed her.
poo is poo, sometimes it's regular sometimes it's not. a snake can digest and excrete in as little as a week, or as long as they want which in the case of blood pythons is long, but a boa not going for a month is no reason to worry too much unless something else seems off.
