Fetal Development – Week 40

Week 40:

This marks the end of the normal gestational period.  The baby is now ready for life outside of his mother’s womb. B y this time, the infant usually weighs 6-9 pounds.

Call or text us today to schedule your ultrasound.

At birth the placenta will detach from the side of the uterus and the umbilical cord will cease working as the child takes his first breaths of air.

The most accurate way to determine how far along you are is to have an ultrasound.  During an ultrasound at ACPC Women’s Clinic, one of our nurses will take measurements to determine the gestational age of the baby.  The first and earliest ultrasound is usually the most accurate of ultrasounds throughout your pregnancy in determining gestational age.
