Smoking for migraines

Erin • Mama to 3 beautiful girls
I am 11 weeks pregnant and I stopped smoking the day I found out we were expecting. 
I usually smoked for my migraines or my anxiety. 
I have headache for 3 days straight.. And I'm wondering if any of you moms have smoked during pregnancy for migraines? It's not something I want to do, but I don't know what else to do for this neverending headache.
