Way back when I thought the pill was causing my migraines. I went off it and the migraines did get better althought they did not go away completely. But I couldn't handle any other type of bc. I hated condoms, heard all the horror stories about IUDs, and never got how a diaphram would be that affective. And all the other types of bc are hormon based too. Anyway so after awhile I went back on the pill but this time I tried a different brand. I have been on it for years now (with the exception of going off it to have a baby) and I have not hand any more headaches!
So it might just be the type of pills you are taking. You might not have the same reaction to a different brand. Just a thought.
