Some people have been waiting for longer. Helper applications take a while to review. However, you might have been denied and just don't know about, because I don't think it notifies you.
Eckho just wait a while and if you get no response then you can just ask a mod or helper to check it out (don't spam and annoy them) like I did. If they want to check it out they can and will tell you if you got denied or accepted.
