Ultrasound concerns

Ok to start my Doctor really isn't concerned at all she's just taking precautions. However, after our anatomy scan she called and said that she wants me to go have a Level 2 ultrasound done. The radiologist noted that our baby has a 2 vessel cord instead of 3, he/she also had a high norm nuchel fold. They measured 5.8 & 6.1. The last thing they noted was that he/she had a shortened nose bone. However my husband and I both have small noses so this one doesn't make her concerned at all! All of this is a little nerve racking and I'm anxious for the 2nd scan. With that said, has anyone had any or all of these results? What was the outcome?
