She doesn't look like she swallowed a softball yet...but in that video you posted on March 2nd, I do see the "spare tire" low on her waist that makes me suspect pregnancy, her behaviours are right on par as well. Is she sleeping on her back yet like a beached whale, does she try to head sleep or curled up, or is she always stretched or sprawled out?
The grooming of the nipples is another big sign as she's making them more accessible for her new babies when they arrive.
Now that we have a starting weight of 343 grams, I am VERY curious as to what her weight will be this afternoon when you weigh her around the same time as yesterday. That and the next days will be key in determining how close she is to give birth.
As for moving babies,, you usually only feel them moving arund in the last few days. They get really really active about 12-24 hours before birth.
Lilith was a baby girl who got pregnant by being forced to live with an adult male. She ended up having 8 baby boys about 5-6 hours later. I had taken a video that morning where they were moving but it was rather dark.

Protein sources like egg, fish, lean chicken are good, lots of healthy veggies, I would avoid acidic fruit as it can cause tummy issues and plenty of a healthy staple diet. Make sure to remove any toilet paper or kleenex from the cage and switch it to paper towel. The former can stick to wet, just-born babies and once it has dried it can peel off theeepers skin if you try to remove it later on.
