Crown to Rump (CRL)
Fetal Weight Standard
At week 17, your baby begins laying down adipose tissue (brown fat), which is essential for body temperature regulation and metabolic energy storage after delivery.
The umbilical cord is growing thicker, stronger, and more flexible, encased in a protective gelatinous substance called Wharton's jelly to prevent compression of vital blood vessels.
