Harmony test. Did anyone else decide to get it done?

megan • My and my husband have been married 4 years. We have the most amazing little 2 year old girl ☺️
I got the Harmony blood test on Tuesday and am so anxious to hear everything is ok with my little one! We also opted to have them check the gender as well. I was excited to find out so early about the gender but someone told me that it's not always right? Has anyone heard of someone getting the blood test done and them finding out it was the wrong gender?
