Watch Your Baby's Growth

Growing Big: Weeks 31 to 34 of Pregnancy

Your baby now weighs about three pounds, roughly the size of a melon. Get the scoop on how much more she'll grow before she's born--and what new developments she's making right now.

Your Changing Body

You may notice more hip and lower back pain than before. This isn't pleasant, but it is normal--it's actually a result of your hormones relaxing the tendons and ligaments near your pelvis for an easier, smoother delivery!

Your baby is almost finished developing reproductive organs and is growing so much that he or she can't stretch out or move around anymore. Your little one will be in the fetal position from now until birth.
