May be normal: There is a laundry list of reasons why women miss periods. Everything from stress to diet to illness. Worrying about why your period is not coming could be a cause as well. If this problem is going on for several months - more than 3 months, then follow up with your doctor. Your doctor will be able to evaluate your hormone levels or look at the several causes of amenorrhea.

Complicated: could be premature ovarian failure, pituitary-hypothalamic disorder, anovulation, asherman's syndrome, there are blood tests, possible x-ray studies and medical consultation that are appropriate. see your doc and get an answer

Missed periods: You are only 16 and you may have periods of irregularity with regards to menses. Is nutrition OK? (any anorexia or exercise bulimia?). PCP may need to do a hormonal panel and a pelvic exam to see what is going on. Poly cystic ovarian Syndrome should be ruled out. Do you have facial hair or worsening acne and easy weight gain? Also, are you on any hormonal therapy such as birth control bills?

Missed periods: You can miss periods from stress, weight changes or heavy exercise, but they should return when those conditions resolve. If you have missed your menstrual period for >=6 months, it is called amenorrhea, and a doctor should test for a hormonal cause. You might need a Provera (medroxyprogesterone) withdrawal test. If no bleeding after stopping Provera (medroxyprogesterone), you might need to start an OCP that contains estrogen.
