Content: During this phase, your baby will grow from a microscopic cluster of cells to a plum-sized fetus with early facial features that might just be starting to look a little like yours. Weeks 1-3
Your pregnancy "starts" on the last day of your menstrual period. Ovulation takes place at about the midpoint of your cycle. The sperm meets the egg and fertilization takes place. The placenta begins to form, and will help nourish your baby until birth. Week 4
The fertilized egg implants in the uterus and begins to develop into an embryo. The umbilical cord begins to form from the placenta. Your little one is about the size of a poppy seed. Week 5
Big steps are under way as the neural tube (which eventually forms the brain, backbone, and spinal cord) develops. The lungs and heart begin to form, and the heart may start to beat.
