Welcome to WHL. I am sorry that you are dealing with so much right now. My only advice at this point is to try not to focus too much on Lupus itself while you wait for your results. Lupus symptoms mimic so many other diseases that until you know for sure, don't panic.
My second piece of advice is this... Remember that there is no single test for lupus and sometimes, even when you have it, it can take a long time to diagnose. You know your body. You know when things are not right. No matter what the doctor says you keep pushing until you find out what is going on with you. Whether it's Lupus, another AI disease or something completely different don't let the doctors push you aside and say there is nothing wrong if you know better.
keep a list of your symptoms. Keep a list with all test that come back abnormal as well. I also had a short history of what happened to me and I always gave these 3 pieces of paper directly to the doctor when he came in the room (never to the nurse to shove in a file). It forces the doctor to actually LOOK at the. And see you as a person not just a patient.
Hope this helps and know that we will be here for you as you try to unravel this mystery
