I fell once and somehow managed to get a hairline fracture in my foot. If your foot is still bothering you tomorrow, you might want to get it checked out.
Per the baby, she is probably fine as she is well-cushioned in there. You aren't far enough along to do kick counts so as long as you still feel her moving -- I'd say that's a great sign all is well with her.
{EDIT: You are better off going with what the L&D nurse says further down in the comments.
