Your Growing Baby:

The testicles begin to descend into the groin from the abdomen; the uterus and ovaries have developed. Body proportions are similar to a newborn's, though the fetus is still thin. The eyes are formed but lack pigmentation. Length: about 11 1∕2 inches; weight: about 1 pound.

Your Growing Belly:

Your care provider should be monitoring your expanding uterus and weight. You should be feeling movement at this point. If you haven't, talk to your care provider. No feelings of movement could be a sign that your placenta is in front of the baby. It may also take more time to feel movement if you're overweight. As your baby gains weight, so do you. You've probably gained at least fifteen pounds by now.

Tips & To-Do's:

Placenta Power

It's not pretty, but it is very important and serves as grist for lore and ritual the world over: Some cultures bury it, some consider it the baby's sibling, some even eat it. Not only is the placenta the trading post between the mother's and the baby's blood supply, at around week 12 it takes over the production of hormones needed to sustain the pregnancy. And recent research found that its structure may even determine the length of a pregnancy. Although the placenta usually functions flawlessly, occasionally a problem arises.
