I feel your pain! Although, due to applying to grad school sort of being a last minute decision, I didn't really get my applications out until January, I still was hoping to have heard SOMETHING by now. All I've gotten are E-mails verifying the fact the schools got my applications. I have gotten a few open house invitations, but these seem to be for all applicants, so I'm not sure how I should read into those.
You are not alone! I try to keep telling myself that very thing, but it feels awfully lonely, haha.
All I can say is, I hope these next few weeks fly by and are wrapped up with some good news : )
