18 Weeks!!

Head to rump, your baby is approximately 5 1/2 inches long (about the length of a bell pepper) and weighs almost 7 ounces. He's busy flexing his arms and legs — movements that you'll start noticing more and more in the weeks ahead. If you're having a girl, her uterus and fallopian tubes are formed and in place. If you're having a boy, his genitals are noticeable now, although he may hide them from you during an ultrasound.
