Week 24

Fetal Development:
The baby gains about 6 ounces this week as the body begins to fill out. This weight is in muscle, bone mass and the growing organs and tissues. The weight could top 1 1/3 pounds by the end of the week.

Maternal Changes:
Between weeks 24 and 28, your care provider may order a glucose tolerance test to determine if you have gestational diabetes. Your uterus is 1 1/2 to 2 inches above the navel.
