Pretty impossible to know. Because of privacy laws, they are typically not allowed to leave info of your results in a voice mail. They could be calling to tell you it was normal, or just that the results were in, or anything else. Try not to stress, it won't change the outcome and you might be worried for no reason at all. :) good luck!
I got an automated call sayn my results were in but nothing else.. i couldnt even hear my results
