To Reach Out or Not to Reach Out...?

So I interviewed with ASU on 12/26. The person I spoke to in the interview said I would likely have a decision within 3-4 weeks. Yet, it's been 6 weeks since then without a peep.

Seeing people getting their A's is making me anxious and I'm just wondering if it would be smart at all to just send an email to Admissions explaining the situation and see if there's anything more they need from me.

Is this a bad idea? Any advice would be great.
