Migraines

I just found out that pregnant! But.. I also found out my migraine medicine is category C. In the past, my migraines have not been helped by excedrine migraine or other over the counter meds. Home remedies have not worked. I usually get them about one a week. If I don't take maxalt or imitrex as soon as see auras I will be throwing up and in bed for at least a whole day. I work full time so I really need some ideas or advice on how to prevent or deal with migraines. I will ask my ob of course but id like to hear from ladies who have experienced it. Thanks!
