Hi I just had a level 2 ultrasound, I'm at 29 weeks and 2 days.. the reason that they sent me to a level2 ultrasound is that on my 1st they found a spot on the left ventricle of the baby's heart.during my visit today, seems like it was nothing to worry about. however, they mentioned that the baby's nasal bone was short and is a possible marker for down syndrome. I am Asian and my husband is asian too.. I'm 25 years old and he's 26, i want to know what are the odds? Can you explain further to me
