SAs typically inform the MOC first — in the case of an offer — and give them a couple days to make the first call if they so choose. Some MOCs call, others don’t. After that, the SAs inform the candidate.
So sure, you can call if you like. But highly doubt they’ll have news for you — because if they did, they’d have already called you.
The much better plan is to put your attention elsewhere — family, friends, school, sports. Patience, patience, patience. Many are in your same situation and many offers are still to come.
