Second Trimester: Images of Your Developing Baby

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. These images reveal all the intricate details of your baby's growth -- from a collection of cells to a full-term newborn. While most women may only receive one or two ultrasounds during pregnancy, which is normal, this slideshow of the 2nd trimester of pregnancy gives you a look at each week of development.
