This is the baby at 3 days old! It is called a blastocyst at this stage.

This is baby at 1 month old. The big dot is the embryonic sac, the little white dot in the middle is the baby. We saw it's heart beating!!!

This is baby at 2 months. It really looks real now. We were so happy to see how much it had grown. It has a huge head, maybe it will become a rocket scientist? We saw the little bud arms and legs moving, and we could see the heart beating, and the blood flowing in the umbilical cord.
