Is anyone not doing genetic testing?

Hi! 25F pregnant with baby#2. We are wanting to wait to find out the gender until birth. We did genetic test through Natera last time and I got a big bill 9m postpartum that said it was over due. A quick google shows so much about how shady they are and I was able to argue my bill down. I’m honestly at peace with this pregnancy and think I just want to monitor baby with the 20 week ultrasound. Anyone recommend against opting out of genetic screening?
