This ultrasound was taken on January 6, at exactly 7 weeks. If you look closely, you can see two small white plus (+) signs. At the top is the baby's head, and at the bottom is the baby's rump. All told the baby measures approximately .7 centimeters. If you look real hard, you can see Joe's best reproduction of the tiny flicker of a heartbeat, as we saw it in the doctor's office
