Nuchal fest ? Genetic testing ? Switching practices

Anyone had these yet ?? Had so much issue with timing the appointments if these and my doc office screwing it up and cancelling my last visit and then scheduling me another location that didn’t do the blood draw and now I have to wait cuz the lady that does it is on vacay. So annoyed 🧐seriously considering switching practices. I’m in a large group practice now which I figured would be easier this time since they should have more options for scheduling but so far it means they chop up all the appointments I had last time and only this tech does this and this perison does genetic blood test etc etc I’m so use to my 3 doc practice that just did it all😤

Anyone change practices ? We moved an hour away so I can’t go to my old one any more where I delivered my first
