First Trimester

Your 11th Week

You'll now be setting up the health care that will support you over the coming months.
Your baby is now unmistakeably human and is undergoing many sophisticated changes, such as development of the sense organs. To mark his new status, he's now called a fetus. If pregnancy hasn't seemed quite real to you so far, it soon will. It's time to get down to such practicalities as your first prenatal checkup. Procedures such as ultrasound scans and blood tests are about to become part of your normal pregnancy routine.
Fetus at 11 weeks
1. The fetus measures 2 in (5 cm) from crown to rump.
2. The ear has started to move into its final position.
3. The neck has lengthened, allowing the baby to nod and shake his head from side to side.
4. The ovaries or testes are beginning to develop.
5. Your growing uterus may begin to cause discomfort as ligaments and muscles stretch to make room.
6. The diaphragm is complete, and your baby can make breathing movements.
7. The placenta will get larger as pregnancy progresses. In addition to allowing food and wastes to circulate, the placenta helps prevent harmful microorganisms and substances from reaching the baby.
8. Within the amniotic sac, the baby is becoming very active, kicking and squirming. You cannot feel any movements yet.
9. The eyelids are sealed shut and will remain this way until the 26th week.
