6 Weeks Pregnant

Your lil' bambino is about the size of a dried lentil (humble beginnings). And I hate to break it to you, but she’s got a tail! But don’t worry, she won’t come out looking like a kangaroo; the tail disappears around week 8.
Still, there’s a lot of action happening in that tiny little body of hers. Let's start with her heart: It's pumping away at over 100 bpm and organizing in a way that will soon resemble four heart chambers.
Speaking of chambers, her early brain sections have developed too! We're talking about the forebrain, midbrain, and hindbrain—the very beginnings of your Baby Einstein.
And if that wasn't enough, the cells of other vital organs like the liver and lungs are on board now, too.
