To do NIPT or not…

I’m 36 and this is my second pregnancy. My first was when I was 30, we did not test and she is perfectly healthy and fine. This time around at 36 I’m considered AMA and have to decide if we want to do the testing. My husband is 39. Any advice, pros or cons…. I’m just scared of false positives and don’t want the added stress but I also like to be informed and we’d like to find out gender this time. First ultrasound showed everything was progressing as it should and baby’s heart rate was 162. Thanks in advance!
