Will my fitbit count jump rope or walking in the spot properly?

I want to burn calories inside my house. Because its cold, im pregnant and i dont have a gym pass right now. I was wondering 2 things.

1. If i jump rope will it count my calorie burning properly?

2. If i walk on the spot will it count them as steps? And if so, is that actually an accurate step? Lifting my legs high and down very controlled while swinging my arms with the steps.

Thanks.
