I'm not sure exactly. I was just trying to speak from my experience, but if it has been a week or so since your last email with the embassy, I would just try to call the embassy on the phone (try to find out who handles Fulbright at that embassy first. For me it was public affairs, I think). Sometimes people are more willing to speak on the phone more freely than to type in an official email. Ask if there is anything else they need, if your host affiliation has been responsive, and if there is anything else you can do on your end. I'd also say to talk to your host affiliation (international office? supervisor? both?) and ask if they've been contacted by the embassy at all.
Yeah it is a pretty scary thing to think about, but the sad reality. I don't know if my case is unique or not, but I know that sometimes, especially in these smaller non-commission countries, the final "decision" can have nothing to do with the application. For instance, last year a girl I knew applying to Bahrain was ultimately denied because of a policy conflict between the president of her university affiliation and the US government - nothing to do with her or her application. That university (after applications were finalized) decided not to support any Fulbrights (or American students maybe? unclear).
Hope this helps. Just speaking from my experience here
