Blood test “Gender test”


So I went to the doctor today and the blood gender test you can get at 10 weeks that also tells for things like down syndrome etc. They said unless your over 35 you have to pay for it. Is anyone else doing this. We are thinking about it but not sure yet because of the money it’s like $200 I really wanna know if my baby has anything so I can read about it and be prepared to help my baby just in case. What do you think I should do?
