H1b dropbox, Stuck at No Status

[dreet]

Dropped off my documents on Feb 13 at Hyderabad. Original appointment was at Chennai

Weirdly on CEAC, the case created date router login is 12th Feb which is a day before my actual appointment and is stuck in no status. usvisasheduling say delivered to post.

It has been 10 days and there is no update yet. Should I be worried?
