Harmony gender success?

Jessica • Positive pregnancy test on September 16, hcg test at 600. September 18, up to 1300. Due May 22, 2015 with boy #3 - Ares!
Has anyone had the Harmony screen test around 10.5-11 weeks and had any success with the gender prediction? The tech told me not to get my hopes up since it was before 14 weeks.
