Your Baby's Growth: Conception to Birth
Congratulations on becoming pregnant! We are sure you are curious about how your pregnancy will progress, and how your baby will develop week to week over the next few months. In this slideshow we will look inside the womb to see how a baby develops through the first, second, and third trimesters. Conception
Step one of conception is when the sperm penetrates the egg to complete the genetic make-up of a human fetus. At this moment (conception), the sex and genetic make-up of the fetus begins. About three days later, the fertilized egg cell divides rapidly and then passes through the Fallopian tube into the uterus, where it attaches to the uterine wall. The attachment site provides nourishment to the rapidly developing fetus and becomes the placenta.
