The Baby in the Belly

Just move the slider under each picture to see how your baby is developing, week by week, inside your womb.

Note that some of these dates are different than what you may be used to. Pregnancy is calculated differently in other countries: This animation is taken directly from our Norwegian sister site. In Norway, they consider Week 9 the end of the embryonic stage; in the U.S., the embryonic stage ends (and the fetal stage begins) at Week 11. They also have one more week of pregnancy in Norway; for an accurate U.S. number, add one week to each number.
