Well it could be pregnancy but if you are going through puberty it could just be that your period is not regulated yet. Stress, illness and/or and extreme change in diet can lead to irregularity of your periods. If your periods have been consistent and this problem persists, you might consider contacting your doctor or taking a pregnancy test.
If your DR has ruled out pregnancy then you need to see a gynaecologist Doctor Who will perform some tests.
