Harmony Blood Test

So I had my test done the Friday before last and still my results have yet to come in. This is my 6th pregnancy but my 1st time ever having taken this blood test. I was wondering if any of you ladies have had this test done and if so how long did it take to get the results? My doctor doesn't call with the results I actually have to call them and I don't want to irritate them by calling every day lol but I need to know because this is mine and my man's last child and he wants a boy so bad and I have a little gender reveal surprise planned for him! please help!!!
