Stages of Pregnancy Week by Week

What My Baby Looks Like in Week 31

In week 31, the fetus weighs about 3 pounds and now your developing baby is beginning to flip and turn inside the womb.

At about 16 inches and weighing about 3 pounds your baby is about the size of a small melon. Your baby is starting to move around more, flip upside down, rotate and even turn its head from side-to-side. Your baby's brain is now more fully developed, with speech and language centers in the process of development. Complex neurological connections and learning will continue throughout the pregnancy and long after birth.
