Hi
Don't worry if your breasts don't feel 'full' - your supply will be settling down from now, and it's quite normal. They make milk on demand and dno't need to fill up before you feed anyway.
It is also very common for one side to make more than the other. It is usually the right side that makes more, for some reason (I was the same). I wouldn't worry about it - you will still make as much millk as your daughter needs.
