Mine are stress and allergy related, been going to the doctor for the past few months to get them under control. Go to doctor about your BP!

As someone who used to go through consistent migraines, the issue generally lies in the fact that either your blood pressure is high or your capillaries in your head are smaller and are making it very difficult for blood to flow. Caffeine is rather helpful with headaches as it enlarges your capillaries for a while.

Also, aspirin is a blood thinner. Which is why a cup of coffee and an aspirin could possibly help you.
