Tests

We scheduled our 2nd appointment for April at the end of my 1st trimester. My doctor wants me to get testing done before the appointment- a blood test and a nuchal ultrasound. They're testing for Down's, trisomy 18, spina bifida, and anencephaly. It's making me a little nervous. None of these run in either of our families although I know it's not always genetic.

Is anyone else getting these tests done? We're not changing our mind on our baby no matter what the results are.
