I hope you're feeling better today! A couple of my migraineur friends did get a headache after the vaccine but not a full-out migraine. I personally did not get a headache with either shot -- my boss who is a nurse told me to take Tylenol before the shots and flood myself with water the whole day. I did that and the only reaction I had (weirdly) was nausea about 5 days after each shot.
