What are my options for birth control methods if I do experience migraines with auras, but they are extremely infrequent? In the past two years, I have only had one migraine with aura. It seems to occur about once every two or so years. I would really like to take a pill or get the shot, but I want to make sure that I am safe. Are there any low-estrogen pills out there or is Depo-provera safe?
