Fetal Development – Week 18

Week 18:

The fetus is now about 5 inches long.  The child blinks, grasps, and moves her mouth.  Hair grows on the head and body.  The ears are now functioning and the baby can hear his mother’s voice.

Call or text us today to schedule your ultrasound.

By the end of the 4th month, the fetus weighs 1/2 pound or more and is 8-10 inches in length.

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.
