She could very well be hungry ! I find that young BP's can be bottomless pits.

I'm not saying you should feed every 2 days, but the young ones should eat about every 5 days and the food should leave a visible lump. Obviously not a huge lump, but a definite one.

I don't always go "strictly" by a chart or a calendar. Sometimes they go through phases where they want more food, then less again. They do a lot of growing at this stage, and go through food faster then an adult who just barely grows anymore.

Can you post pictures ? With something in the picture as size reference. Like a soda can next to the snake or a pencil.

If your temps and humidity are up to par and this is a young/growing snake that is feeding well...I'd say the restlessness is "looking for food".

imho
