5 weeks pregnant

At this stage, I am what you would call an embryo. Embryo means "something that grows". Cool, right? The embryo consists of three layers of cells, where each layer will form different parts of my little body.

The top layer forms the brain, nervous system, and skin. The second layer forms legs, muscles, blood vessels, and cartilage, while the third layer forms the stomach, intestines, and liver. The part which will eventually be my nervous system, spine, and brain will develop this week. Isn’t that fascinating? The coming weeks, up to and including week 10, are very important as all my organs will be formed during this time.
