In the meantime, I would recommend sending in your transcripts because if they're going by snail mail, it might take a week or two for them to process that. And they need your transcript to verify your application.
And let me add that you should send all your transcripts. If your primary transcript shows classes taken at another school, you will be asked for a transcript from that other school. Be proactive in getting those transcripts to AMCAS to avoid delays.
