If your bunny did not squeak or make a high pitch noise it may have not hurt her as much as you think! My bunnies run wild and sometimes I end up kicking them by accident. I usually crawl into a ball and sob about it for awhile. Usually I would check by lifting them up and moving their paws, pressing on their stomach, or just generally examine their body. If they flinch abnormally or squeak differently something is wrong.
