It could also be high/low power fronts, change in hormones, certain foods. My neurologist had me keep a trigger notebook. That really helped cut down my migraines. He also said normal OTC meds can cause it. Tylenol causes rebound migraines for me.
I'd talk to him and see if the two of you can work out a way to identify your triggers. Good luck.
