I'd probably advise against it (partially out of sympathy for the person in charge of admissions who is probably flooded with inquiries from nervous applicants at this time of year). The most I can see you getting out of it is a response that says you should wait until the official result, which may well be tomorrow. It's stressful, I know, but I think you have to just grin and bear it until the official result comes in.
Full disclosure, I say that from a position of being admitted somewhere (unreported Madison admission) so I'm less stressed about not hearing back from schools and I'd totally understand your position if you sent off a few inquiries.
Good luck!
