Was the stroke on the opposite side of the brain as your focal neurological deficit when you have your migraine. Unfortunately, you are at a
higher risk of having another stroke
the general population. If you have an aura with your migraine, you at even a higher risk (although the risk is only alittle). I would make sure that you do not have any other risk factors for stroke, antiphospholipid antibodies, Leiden V factor, prothrombin mutation, abnormal low HDL or high LDL, etc.
