In brief: Not ovulating
At age 12 almost all girls are still early in establishing their menstrual cycle, and they are usually not ovulating consistently.
While this is happening, and it can go on several years, her periods will be irregular. At age 12 this is not unusual and is rarely a cause for worry.
