Desperate help

Am
Okay guys, kinda a long shot. 
Before I got pregnant, I used to suffer really bad migraines and nothing would work except sometimes cambia which isn't safe to take while pregnant. Now I'm 18 weeks 2 days and have had migraines for the past 3 days non stop y'all. Tylenol won't work, any suggestions? I'm taking Tylenol to reduce my acute fever but it's not getting rid of my migraines :(
