You rarely have a period and you have excess body hair. If you're underweight or are a serious athlete, that could be the problem.
Some athletes skip periods or have their periods cease altogether. Very thin women can stop having periods; they also grow more hair as a result of the low weight.
If it's not either of these, you may want to go on birth control to regulate your periods and get you back to having a period every month. However, this won't help you when you decide to start a family.
You do have some of the symptoms of PCOS but weight gain is also a common symptom of it so it's important to know your weight.
