Is it possible for you to be going into pre-menopause or menopause? There are several factors that can interfere with a period. Examples; stress, weight gain/loss, medication, illness, climate, cyst, or polyp of the cervix.. just to name a few.
If you don't feel any of the above would apply for your situation, then you should have an exam to make sure there is no type of infection, std etc. going on. At the time of the exam your doctor would be able to give a more accurate answer. You may need a hormone or get your system balanced again. Having a period every couple weeks could bring your body to an anemic stage. Since your doctor knows your medical history you should start there.
