We got Ariel when she was 10 weeks old as well, and she was used to going on the pee pads already. At 6 months old now, she goes on her pads 95% of the time. When we got her, she got a small portion of the bedroom; as she got older and knew where she needed to potty, her "space" increased. She now gets to roam the entire upstairs, but I still don't give her free roam of the entire house. Not till she knows where to go 100% of the time.
Not much help, but good luck with potty training her. It's so frustrating when they're this young, but it's worth the patience
