At home migraine remedies!

Please help. I've suffered from migraines before I was pregnant. Now I'm 15w3d and I've had a headache for 4 straight days. I've taken Tylenol, which helps for a small period of time but it doesn't completely take away the headache. I go to a nursing school and I asked one of the teachers about it today and she said Tylenol is okay, just not in excess. So I'm trying to refrain from that since I've taken it off and on the past few days. I'll suffer if I have to for my baby but I just want some relief so I can sleep. Anyone have any safe at home remedies? Something simple that I'd have at home. Please!
