Harmony Test (Early Gender Reveal)

Amy
Recently went to doctors to inquire about getting Harmony Test (the blood test that's usually about 175 out of pocket) to find out baby's sex very early.  
My doctors office said they will NOT let their patients use that test anymore.  I was very disappointed and thought that was an extreme measure if I wanted to do self pay for it to find out sex early.
Anyone else have their doctors office no longer writing for the Harmony test?!?
