NT Scan January 30th

I have my "NT Scan" On January 30th {This prenatal test (also called the NT or nuchal fold scan) can help your healthcare practitioner assess your baby's risk of having Down syndrome (DS) and some other chromosomal abnormalities as well as major congenital heart problems.The NT test uses ultrasound to measure the clear (translucent) space in the tissue at the back of your developing baby's neck. Babies with abnormalities tend to accumulate more fluid at the back of their neck during the first trimester, causing this clear space to be larger than average.} I am not too worried about my Baby having down Syndrom, but the OB/Gyn will also take a look at the Babies brain, and i think every mother, who had a baby with brain abnormalities, is scared of this scan!. Sticky beans head looked normal on the ultrassound so far, but there are different stages of "Anencephaly" some might have a "normal" developed Head / scull but the brain is not developed, or maybe it isnt Anencephaly, but something else that involes abnormalities of the Brain....... So i am terrified but happy at the same time. Happy because we get to see sticky bean again, terrified because we dont know the outcome of this scan. I have faith that our baby will be happy and healthy but there is this little nagging voice in the back of my head saying.... WHAT IF........
