I have never been pregnant and I haven't had my period since February. I'm really scared that I'll never be able to have children. Can I? What's wrong with me?

Whether you can have a baby can depend on whether you are ovulating. Since your haven't had a period since February, it would be wise to see your doctor. There can be a number of possible reasons for a lack of periods, each requiring different treatment. A complete physical would be the first step.
