This young lady should see a gynecologist to evaluate her condition. Irregular bleeding at age 22 is usually a signal of some form of hormone imbalance. After a history and physical, the doctor would want to check certain labs related to blood count, thyroid function, FSH, LH, and possibly her blood sugar (rule out diabetes). Fortunately, this condition is rare to be an infection and extremely rare, cancer. Good also is the fact that most cases of irregular bleeding can be treated with improved nutrition, exercise, and medication when needed.

All the Best,
