Genetic testing???

I'm almost 9weeks and had an ob appointment today and they said I have a choice of whether or not to have genetic testing done ! When I was pregnant with my daughter 3years ago they didn't give me a choice they just said at 12weeks I'll have a NT scan and some blood work so that's what I did. I told my doctor now that I just want the same thing that I had with my daughter and she said it was called a sequential screening did any of you guys have to do this too ???
