Since you have been sexually active and you have missed a couple periods I would highly recommend taking a pregnancy test. You can buy one over the counter at any grocery store or pharmacy. They are really easy to use and give an accurate result.

If you are pregnant, you need to speak with your doctor as soon as possible. Being pregnant at this age can bring increased medical risks. You doctor can talk to you about your options as well, like whether or not you want to parent, as well as make recommendations for counselors that specialize in these situations.

But try not to worry too much until you take a test.

It is very likely that you missed a couple periods due to being so young. Your cycle will not be regular for a few years now and you can except some abnormalities for now. But, since you have been sexually active within the last six months, taking a pregnancy test is a priority to rule out pregnancy.
