NT scan

Cailyn
Had our NT scan yesterday and the membrane behind baby's neck was larger than normal so they had me come back in today. They re-measured and it was measured not as large as yesterday but still larger than normal. They drew my blood to see if they may have Trisomy 13, Trisomy 18, or Down's syndrome. I also have an echo cardiogram in December to make sure nothing is wrong with the heart. 
This is my first baby so of course I'm worried. I just wanted to ask if people had the same thing and baby came out fine with further testing.
