When you left the message did you ask for any response on anything? Or was it just a hello, I'm doing fine, just called to see how you are doing type message?
Maybe she was just happy to get the message, wasn't in the mood for a chat there and then and forgot about it. Don't get too discouraged. If there is no response, then wait a week and throw out another line see if you get a bite.
If your floundering flip back to concentrating on you for a few days.
