Pregnancy migraines

Anyone else getting migraines during their pregnancy? I'm 15 weeks and they started about 2 weeks ago, barely going 3 days without getting one. They make me nauseous sometimes to the point of vomiting, unable to function or get anything done when they come on. Tylenol rarely helps. Warm baths sometimes ease the pain while I'm in it, but comes right back when I get out. I also had this with my last pregnancy 8 years ago and never found something that worked for me. Anyone have tips?
