Hi, no need to worry. I've also had Oscar b4. My baby's 頸皮is 3.5mm, since i've pass the blood test. I've also unhappy. I've cried many days for this event. 24 hrs non stop cry. Later i also done another test - 抽絨毛球, luckily everything is ok. Now my baby is nearly 2 moths la. See from the photo, he is very cute and healthy.
