Sorry these are not in order, they probably never will be, but I will at least try to feel you in on what they are. On the US the smallest blurb is the baby, the larger one is the yolk sac. This was the first time we saw your little heart beating baby. It is 128. We get to hopefully hear it in 8 more days. That is our next appointment with DR. Johnson. We sure have been to so many appointments already with you. Just shows how important you are to us.
