Genetic testing

Just curious to hear your thoughts about it because I’m on the fence of whether or not I should get it done. Do you feel it’s absolutely necessary? I want to hear thoughts from those who have gotten it done and those who haven’t, thank you. At this point I would want to have my child regardless, so I feel like getting the testing done could add unnecessary stress to my pregnancy, but this is also my first pregnancy so I’ve never been through this before and that is why I would like to hear from you all.
