Week by Week Pregnancy, 9-12 Weeks Gestation

By the end of week 12, your baby will be about the size of a plum and 2 inches in length! He or she now has visible ears & eyes, organs, & functioning joints to move about, even though you will not feel your baby's movement for another month or so. A sonogram may show your baby sucking his or her thumb and responding to stimuli! While your baby's critical development is complete by the end of week 12, the growth and maturation of your baby's systems will continue during the following weeks.

You should begin to feel less tired and nauseated by the end of week 12 in your pregnancy, but may now feel light-headed and develop headaches from changes occurring within your body. Continue to drink plenty of fluids, get rest, and eat healthy as your body is adjusting to many new changes. Finally, it is very important that you communicate with your pregnancy doctor about symptoms that you are experiencing for your and your baby's health and safety.
