I am 24 years old am in my 21st wee of pregnancy. during my ultrasound a hyperechogenc bowl was detected and i have done a more thorough test for downs syndrome, and have been told that the bone structure of the baby is normal. we are awaiting results for cystic fibrosis. My main concern is that can a child still have ons syndrome if the bone structure appears normal atthis stage?, also what are the other results of chromosome abnormality as i am certain this baby has some issues... its uch a long wait til december to see the baby myself.. ant relax til i have some clear avenues. please avice!
