Migraine relief

I had migraines all the time before I got pregnant and I'm currently 17.5 weeks and tonight I had my second migraine since I've gotten pregnant. I used to take 100mg of sumitripton before but now I obviously can't take that. Does anyone have any tips or tricks to get rid of these suckers? The only way I could kick it was by sleeping it off but that involved me having to leave work early because I was in so much pain. Thanks in advance!
