4 weeks pregnant

The foundation for the future child (me!) Is now being laid and an intensive cell division is underway. You can see the contours of the basic structure of what will later become my digestive system, my blood vessels and my lungs. The placenta has begun to form, but all the nutrients still come from the so-called yellow sac.

Despite the intense activity in the womb, my mother probably does not notice the pregnancy yet. But now I'm on my way!
