Your body changes a lot during pregnancy. A variety of symptoms emerge--from morning sickness to stretch marks and everything in between. In order to grow a baby, your body does some hard work!

Another symptom is the dark line that many parents develop on their abdomen when they're expecting. It's technical name is the "linea nigra" or "linea negra," which literally translates to "black line." It's dark in color, about a quarter inch wide, and runs vertically from your pubic area to above your belly button.
