Could an umbilical cord snap during the first month?

Not much of a cord: During the first month there is a lot going on in development but there is not much of a cord as you may visualize it. A lot of the embryonic work goes on in a mass of tissue attached to a thick stalk. At about 30 days a crude cord is forming. The fetal cord has the ability to grow longer under tension. I've seen one 9 feet long compared to the nl 3. The only one i know snapped happened @ birth.
