Your baby's vocal cords are beginning to form. Not long more and your baby will be able to make sounds!>
Reflexes are being developed, and the hands are becoming more functional.
Sockets for all twenty teeth have formed in the gums.

Your baby's liver begins to carry out its functions of cleansing the blood, storing nutrients, and providing needed chemicals.

Intestines have moved from the umbilical cord into the body.
The tail has completely disappeared.
As your first trimester comes to an end, most of the difficult early symptoms are over (or soon will be).
The risk of miscarriage is also greatly reduced now, so sit back, relax, and enjoy the rest of your pregnancy!
The pregnancy hormone hCG has been increasing oil gland secretion (which sometimes results in acne). Together with greater blood volume in your blood vessels, your skin may look smoother and more flushed, which some call the "pregnancy glow."
