Week by Week

Week 13

This week of pregnancy, your baby is about 2 - 3 inches in length (crown-to-rump) and weighs close to 1 1/2 ounces. Your baby's face has a distinctly human appearance and is really starting to look like a little baby. Your baby's chest is rising and falling as he or she practices breathing movements.

All twenty baby teeth are formed and waiting beneath the gums until well after your baby's arrival. Vocal cords are now developing in the voice box, forming the larynx, even though your baby won't be able to make any sound until after birth. Your baby has many reflexes and squirms inside of your belly, as well as turns his or her head from one side to the other.

Your uterus has grown quite a bit and loose-fitting clothes may be much more comfortable by now. You aren't extremely big yet, so you're probably feeling quite comfortable. Your appetite will start increasing, as your nausea fades into only a bad memory and you may begin to feel a little less tired.

You may notice that your sense of smell has become more sensitive and some women even notice an odd metallic taste in their mouths which affects the taste of foods. These likely are caused by changes in your hormone levels during pregnancy.
