Did not read all the replies, so if this as covered, sorry. What test are you getting? Finding out the sex is standard with some and not others. When I had the Harmony test with DS I thought we were going to get sex info but was informed later that was an additional test/box that needed to be checked. Pretty sure it is standard with the M21 test.
I wanted to know by the DNA since there is less chance for error with that.
After an abnormal NT ultrasound we had a CVS done and sex chromosomes are checked in that. At first we asked them not to tell us but after getting a second set of normal results we asked the genetic counselor to mail us everything. We took it to the bakery and had them make a cake. We cut it the next night as a family. It was perfect
