Obviously, the agent should contact you the moment she has an offer (or a home she thinks might be right for you). The question is what happens when nothing is happening.

You should hear from your agent enough to quell your fears and to strategize about the price and marketing strategy (or whether to widen your search area because no homes are available in neighborhoods you desire). Generally, those conversations take place weekly, but you should know what to expect because lack of communication is where real estate relationships falter.
