14 Weeks After Conception

Your little sweetie is about 4 to 4-3/4 inches long from the new fine hair on his head to his bum. He weighs about 3 to 4 ounces -- that's about as much as your average kiwi fruit!
His head is now erect, and those tiny arms and legs are developed -- and his fingernails are also formed. His muscles begin to move energetically. In fact, starting this week, your baby's movements -- like him kicking and punching and sucking his thumb -- can easily be seen via ultrasound. (Soon, you will be able to feel them yourself.)

His skin doesn't yet have color -- it actually looks pretty transparent, and the veins and arteries are clearly visible.

Here's a closer look at what your baby may look like right around 14 weeks after conception, or at 16 weeks menstrual age.
