Often, pages that finally appear in the SERPS with a fresh tag are volatile and when the fresh tag "elapses" the page reverts to where it was. Though the upside is that Google will probably be back.
For the moment, chill out. Sites that aren't massively high in the PR scale don't get serviced that often, and a period of time equal to what you've already mentioned may well see you move from "fresh" to established and therefore slightly more stable. DerekH
