Creamy, yellow cervical mucous is generally normal. You can learn more about what's going on in there on this site:

A tell-tale sign of a yeast infection is: "Unusual vaginal discharge can range from clear to white, and appear lumpy or curd-like. While the discharge, if present, may look "chunky" or "cheesy," it rarely has a strong fishy odor like other vaginal infections." The lumpy/chunky part is the most important. Learn more here:

if its smelly burning itching I think you may have an infection go see your doctor :)
