Last year I was told I was high risk for spina bifida and trisomy 21. I had to go thru 2 weeks of living hell until I could get my level 2 ultrasound. They have certain markers that they are looking for and can tell right away if your baby looks like he/she has it. Once I had the ultrasound they told me I didnt show any of the markers, and I gave birth the the most beautiful little girl I have ever seen, she'll be 1 yr old next week

Since they didnt see the markers I declined to have the amniocentesis, but had to go back for a 4 chamber heart scan just as a routine procedure.
