Migraines and pregnancy

So I'm 5w+4d. And I have a history of chronic migraines. I usually take excedrin migraine and it works great! However, excedrin is a no no during pregnancy. I've been taking tylenol instead. It hasn't worked for me at all. I've gotten 3 debilitating migraines in the past 36 hours. I don't know what else to do. Any of you ladies had the same problem? What works for you? I'm up for anything at this point!
