Can iron supplements cause migraines?

I am not: Aware of any association between iron supplementation and migraine headaches.

Maybe anemia: Im not aware of iron causing migraines however there is an association between migraines and anemia. We often see women your age with heavy periods often from uterine fibroids which can commonly cause migraines. The anemia is often first treated medically with iron supplements. Do you have heavy periods? Change pads more frequently than every 3 hours? Are your migraines worse with your menstrual?
