i think there is nothing wrong with you!but if you haven't gotten your period more than 2 months,you should be worried and eat some pills or go to a doctor..........
If you are on birth control pills, the pills could be too strong, or just the wrong pill for you. There are other factors that could cause that, such as a hormone imbalance. It is best to go to your gyn dr and be checked. Just know that no period does not especially mean you can't get pregnant during that time. Though you are not sexually active it is a good thing to know. Let me know how you do. Best of Wishes for a speedy recovery.
