Hi, I am 37 years old and 14 weeks pregnant, my NT scan is done in 12 week 4 days.Everything was  normal except absent/hypoplastic nasal bone. The doctor told me to do it again  @ 14 weeks in that everything is normal but the right nasal bone appears to measure 2.1 mm and left is absent / hypoplastic. The double marker test was low risk. The doctor suggested NIPT at 16 weeks. My question is can nasal bone grow in future? If the NIPT test report came at a low risk should I worry till the birth of this baby? Is this possible a double marker test report low risk and an NIPT test came High risk?
