When you're pregnant, a whole new part of the English language opens up. Suddenly you're obsessed with placentas, trimesters, and sussing out whether you should go with a sonogram or an amniocentesis to determine baby's gender. And then you hit the ninth month of your pregnancy, and a new term pops up: cervical dilation.
It refers to the opening of the cervix, the part of the body that separates the uterus from the vagina, and according to Dr. Robert Atlas, an OB/GYN at Mercy Medical Center in Maryland, dilating is part of the body's way of getting ready for delivery.
"As you get closer to term, the body knows to start contracting and opening of the cervix begins," he explains.
