There are several causes for irregular periods. Examples; stress, weight gain/loss, medication, illness, climate, cyst, or polyp of the cervix, hormonal imbalance, thyroid, infection.. just to name a few.
Without a proper exam it would be hard to pin point the exact cause. Since you are already late, I would suggest confirming your test results via a blood test with your doctors office as this is much more accurate than a home test.
