You could also try telling her what you're feeling now. You could tell her that it's been a few days now and that you're wondering what she thinks of what you told her. If she really loves you, though, she won't break up with you. It's okay for you bring up the topic, too, and not wait for her to. Being bi is kind of a large part of who you are, I think, and so I think it would not be very good if that was to always remain an awkward topic to bring up with her.
