You've grown 10,000 times your original size to 1/4-inch long. Your brain now has human proportions. Blood flows in your veins but stays separate from your Mom's blood.
Your pituitary gland is forming. Your mouth, ears and nose are taking shape.
6 weeks, yet alive at this moment, a just removed tubal
pregnancy.
Your brain waves can now be measured by an EEG.
Your skeleton is formed. Your brain now coordinates movement of your muscles and organs. Your reflexes have begun to kick in. If you're a boy, your penis is forming. Your Mom now misses her second period. And you (not your penis) are about a half inch long.
You've begun to move spontaneously. Your jaw forms, including teeth buds in the gums.
Your lips are sensitive to touch and your ears may resemble family patterns.
