Music Industry Discussion

I have submitted my most recent CD to several reviewers at various websites, blogs, and magazines.
How long should one expect to wait until a review is completed? A week or two, a month, a couple of months?
Is there an average?
Also, should the artist send a follow up email asking if they received the CD?

I appreciate your response, but that doesn't really answer my question. I did present myself in the way described there.
I was just wondering how long artists usually wait for a review to come out.
