The mini pill such as Cerzette is thought to be safe for women with migraines. I doubt that your symptoms are due to the Cerzette, but just to be safe, I would consider stopping the Cerzette for a while and see whether they disappear. It the symptoms are gone while not taking cerzette but return when re-starting it, we'd have to conclude that the pill is responsible.
However, I think that it's more likely that this will not be the case. If your symptoms continue while off the Cerzette, then I think we can conclude that there is no relationship, and then you can take the Cerzette with no worries.
If your symptoms really seem to be due to the Cerzette, I would talk to your doctor about trying a different mini pill. Best wishes.
