There are several reasons why you may have missed your period many of which are not serious. However, if you miss more than one menstruation cycle it is advisable that you contact your doctor to discuss the issue.
The cause of a missed period is most commonly due to pregnancy, though as you say you are not sexually active this is clearly not the reason. Others factors can also have an effect on your menstrual cycle. Stress, changes in weight and strenuous sport related exercises are a few of the most often cited explanations. Other causes can be breast feeding, the discontinuation of oral contraception and menopause, although, again I don't think you need to worry about those. One serious cause for your missed period could be an ovarian cyst, so it is important that you contact your family doctor should you continue to miss your period.
Missing a period is referred to amenorrhea in medical terms and comes in two classifications, Primary and Secondary. I believe, if at all, you would only be affected by Primary amenorrhea. Primary amenorrhea, where the problem is menstruation cycles never starting, can be caused by developmental problems. Conditions such as the congenital absence of the uterus or failure of the ovary to receive or maintain egg cells are common examples. In addition to these reasons, a delay in pubertal development can also lead to primary amenorrhea. According to the website menstruation-info-with-doc.com it is medically defined as "an absence of secondary sexual characteristics by age 14 with no menarche (first menstrual cycle) or normal secondary sexual characteristics but no menarche by 16 years of age."
It is not unusual for a woman to miss, or skip, a period throughout her life, but if you are worried you should seek medical advice.
