Your Pregnancy Week by Week: Weeks 13-16

(continued)

What's Happening Inside You?

Your baby's fingers and toes are well-defined; his or her eyelids, eyebrows, eyelashes, nails, and hair are formed. Teeth and bones become denser. Your baby can even suck his or her thumb, yawn, stretch and make faces.

The baby's reproductive organs and genitals are now fully developed, and your health care provider can see on ultrasound if you are having a boy or a girl. You don't have to find out the baby's sex yet -- that's up to you.
