Your Growing Baby:

Your baby is about as wide as your palm, about six inches tall, and weighs about four ounces—about as much as a bar of soap. She now weighs more than your placenta. Your baby is now covered with a downy layer of lanugo, which swirls in fingerprint-like formation over her whole body. Her skin is still thin. Brown fat, a special type of fat that plays a role in body heat generation, is being deposited. In the next few weeks, your baby's eyes will begin to move beneath their fused lids in a side-to-side sweeping motion.

Your Growing Belly:

As your breasts grow, they'll be sensitive and tender and sometimes just plain painful. The placenta is now a fully functional network of blood and tissue that distributes nutrients and removes waste.

You're looking pregnant, but not so much that it's difficult to put your socks on. You may even get that pregnancy glow, a radiance that comes from extra blood flow to your skin. And you'll start to feel a lot of the baby's movements soon.
