Harmony Bloodwork for gender/genetics

Tori • Happily married to my best friend! Environmental Chemist/Wastewater Treatment Plant Manager.
I went to my dr last week for my 1st appointment and they told me I could come back this week and have the genetic blood work done and to determine gender. Called this morning and she told me she thought my BMI was too high for it to work at 10 weeks? I was just looking for other women who had this bloodwork done and if they had any luck. Thank you!
