What happens if you have a aura then a migraine , will it keep happening . like every 2 weeks or so or could it be just a 1 time thing ?

Aura with Migraines: The pattern of auras in relation to migraine vary a great deal between one person and another, and also between episodes in an individual. A person may always have an aura prior to a migraine, may sometimes have migraine with an aura or may have an aura without a subsequent headache. The best predictor is your own history.
