MONTH ONE

For the first six weeks, the baby is called an embryo. The lungs and brain are starting to develop, and the tiny heart will begin beating on the 25th day. To protect it from bumps and pressure, the embryo is enclosed in a fluid-filled sac, which will grow into birth. The umbilical cord is also developing, made up of blood vessels. The cord will carry nourishment from your body to the baby and carry away the baby’s waste.
