I'm 36 and 8 weeks along (will be 37 at the birth). I have a healthy 2 year old. I had my first OB appointment today and they suggested the Maternit21 test. Other than my age, I don't feel I'm at much risk for the chromosomal abnormalities, so I'm not sure I want to do the test.

Did anyone decide not to do any of the new blood tests? What was your reasoning?
