First Trimester: Images of Your Developing Baby

Do you know what to expect in the first trimester of pregnancy? We've partnered with the American Institute of Ultrasound Medicine (AIUM), Johns Hopkins, and the March of Dimes to create this unique peak into Baby's development inside the womb during the first trimester. These images reveal all the intricate details of your baby's growth. While most women normally receive one or two ultrasounds during pregnancy, this slideshow of the first trimester of pregnancy gives you a look at each week of development.
Week 8 Week 8 of Pregnancy

Fetal Size: Length, 0.6 inches; weight, 0.04 ounces.

Fetal Development Milestones: Baby's hands and feet are developing. Fingers are beginning to form, but are still fused together. Elbows and ears taking shape. Baby-to-be's body, arms and legs are getting longer. Small, jerky movements (seen on sonogram).

What You're Seeing: In this image, the embryo is lying on her back with her head to the right of the screen. In this now familiar c-shape, you can see that the baby-to-be's head is becoming larger during this part of the first trimester to accommodate her growing brain. Her brain is divided into three main parts: the forebrain, the midbrain and the hindbrain. As in the previous week, the hindbrain may be seen as a dark area in the back of the embryo's head.
