Annie, a follow-up should be automatic for something like this.
Just make sure they won't perceive it as bugging them. Wait the mentioned time period (which you have), and if you speak with the woman you met with, make your next move depending on what she tells you. If you have to leave a message, wait again for a few days or so and then call back again.
There are any of a number of reasons they may be interested but have yet to call you, the obvious one being that they may have misplaced your contact info.
Hey, it's been known to happen...![]()
