If it helps your anxiety then do it! 2 week wait is bette than 6 month wait - advice from my Gynae :) and also if financially you are able. And if you are going to keep the baby no matter what, some people don’t do it. But also good to know to prep yourself :) hope this helps!
If it bothers u, and wish for a better accuracy, then go for harmony. At least for me, once i did that, i no longer worry about the inaccuracy the other test may bring.
If u are worried den u should. But if u are not going to mind whatever the result is, then no nd ah.. just tht with harmony, u will also know the gender
It’s better to do especially you are high risk (age?) pregnancy.. Just share with your gynae I’m sure she/he will share more..
If ur age is 35+ n u have any genetical doubt u may better to go on .. check with ur gynae
