am 32 years old this year. I am 23 weeks pregnant with my second child. I went for a check-up and all the indicators are normal except for the baby's nasal bone measuring 5.5mm. The doctor said that the baby's nose is a bit shorter than the standard, because at week 20, the baby's nasal bone measured 5.2mm. I did the Double test at week 12 and the risk was low at 1:547. So doctor, can you tell me if a 23-week-old fetus has a short nasal bone? Is my baby likely to have Down syndrome? Is the NIPT test accurate now?
