The Third Trimester

Weeks 27 thru 32 Gestational Age

The fetus really fills out over these next few weeks, storing fat on his body, reaching about 15-17 inches long and weighing about 4-4 ½ lbs by the 32nd week. The lungs are not fully mature yet, but some rhythmic breathing movements are occur. The bones are fully developed but are still soft and pliable. The eyelids open and can even respond to light.

Weeks 33 thru 36 Gestational Age

Your baby will begin to move down into the head-down position preparing for birth. He or she is gaining weight more rapidly. The fingernails and toenails are formed, and you might have to file them soon after birth. The fetus is now 16-19 inches and weighs anywhere from 5 ¾ lbs to 6 ¾ lbs.

Weeks 37 thru 40 Gestational Age

At 38 weeks the fetus is considered full term and will be ready to make its appearance any day now. Mom may notice a decline in fetal movement as your baby now takes up so much space in your uterus that it has little room to move. The mother is supplying the fetus with antibodies that will help protect against disease. All organs are developed, with the lungs maturing all the way until the day of delivery. The fetus is about 19 - 21 inches in length and weighs anywhere from 6 ¾ lbs to 10 lbs.
