Content: 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. You might get to hear it via ultrasound sometime between week 6 and 12. The amniotic sac has formed and is filling with amniotic fluid, which will help protect your baby throughout your pregnancy. This might be when you suspect you’re pregnant — time to take a home pregnancy test and schedule a visit with your healthcare provider. The embryo is about the size of an orange seed. Week 6
The embryo is now huddled up in a curved C-shape.
