Your Baby
By this time your baby has a pretty good chance of surviving outside the womb. The eyes open and the retina form different layers which can sense light levels and send messages to the brain. Also, the once smooth surface of the brain starts to form grooves and indentations.
You
Your hormones just won't leave your skin alone. Now you may be noticing pigment changes galore: a line from your navel to pubic bone (linea nigra), darker freckles, moles, and nipples. You may even experience something called the "mask of pregnancy," where the skin darkens on the sides of your face and around the nose. These are all normal side effects of pregnancy, and the darkening should fade after you deliver.
Here are some tools you'll need as you go through pregnancy. Use the baby name finder to help you choose a great name. Want to know when to expect your newborn baby?
