Sorry, this is probably not going to be comforting...but the system is not designed for the applicant's comfort. I see this here a lot -- "I submitted X two weeks ago, why haven't I heard anything.." USNA has thousands or applicants, and this is probably the heart of the Admissions process....information is flowing in continuously. DODMERB serves all Service Academies (and I think ROTC as well). The Admissions Officer's are busy dealing with the 100's of emails and calls they receive daily, and probably are impatient with calls from candidates that are simply looking for assurance that all is in order.
My advice is to be patient, but remain vigilant --if the portal is not updated in a couple weeks, Email Admissions to ensure that it was not somehow lost. If you don't here from DODMERB soon, again email the Admissions Counselor. If you don't get responses, you could ask the BGO to reach out and find out whats going on.
