18 Weeks

My baby bump definitely feels bigger! Here is what is happening this week: Head to rump, your baby is approximately 5 1/2 inches long (about the length of a bell pepper) and weighs almost 7 ounces. The baby is busy flexing its 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.
