Week 7 Pregnancy Ultrasound

The mother’s body is changing and the baby is growing. During this week, both the uterus and the baby have almost doubled in size from the previous week. At 7 weeks, the embryo is approximately the size of a tiny blueberry. Week 7 is a week that many developmental stages are met. Some organs are being created, while other organs are getting their start at the work they will continue to do throughout the duration of their lives. Many body structures are still vulnerable in their stages of development, including the nervous system and some major internal organs.
