What does this notice mean???

So far I have only received the initial text message saying they received my I-129F at the lockbox and they are forwarding to VSC. This was on 4/6/13. So I got to the uscis site tonight and enter the receipt number and I got the following message. Is this normal? I haven't received anything about NOA1 yet. Thanks!

Initial Review

On April 12, 2013, your Alien Registration Number was changed relating to your I129F, PETITION FOR FIANCE(E). Please check our website at www.uscis.gov for further updates on your case. Please wait until the end of normal processing time before calling customer service at 1-800-375-5283 for live assistance.

I think you just haven't received the hard copy of the first NOA yet. I got that message on the website the same day I got my notice. So, it's officially started. Congrats.

I had received the same message a while back. Called and asked them why and was told that because my fiancée's mother sent in a petition for him prior to me sending in mine, that they had changed his previous Alien# associated with her petition and changed his Alien # relating to the I129F that I had filed for him. Not saying this may too be the case for you, but that is what they explained to me. Good Luck on your Journey :-)
