pregnant with a migraine

I'm 7 weeks pregnant and I have really bad migraines. This is the first one since I've found out I'm pregnant. So my doc prescribed me vicoprfin but I didn't like taking them and I was told to try taking BC's which worked perfect everytime.Those were the only two things that ever helped! But since now can't take a bc I don't know what to do. I just took a hot bath with menthol Epsom salt and it eased it off but not completely and I feel it coming back. Any advice on what to do, specifically tonight, bc I'm not able to go get anything this late. But I'm going tomorrow to town and I'll get some things to help when I get

another one. So please any ideas on what to do would be great!
