No News is Good News

I called the doctor's office today to see if the results from my blood work had come in. They said that no news is good news. So does that mean they got the results and everything was normal or that they just haven't got the results back? I'm not sure that makes me feel any better. I'd still like some answers. Like if the tests did come back normal why am I tired all the time? And if the results have not come back yet... how long until they do? If I need a bone marrow biopsy then I want to know that... and get it done as soon as possible. Now back to playing the waiting game.
