Cervix position- difference between high/low?

Kelli • Married since 2005, and had our first child on June 16! We are so in love with our little boy!!!
When referring to the position of your cervix, I need help determining what high and low means.  Is high actually UP, or positioned back toward the tailbone?  Positioned forward like toward the front of the body?  I have no idea what I'm feeling when poking around in there!
