No, there is nothing you can do. She hasn't outright stolen your design, it's clear her design has a very similar idea, but it looks like it's made from scratch. Even if using someone elses idea to create something broke a rule, it would be quite hard to accurately prove who created theirs first I think. Even just seeing who created the original when they have the same design can be hard unless you use photoshop and have the original photoshop file, or similar program that can do the same thing.
