Birth control causing headaches

Loraashley
My I am currently on mirecette And previously before that I was on orthotrycyclin low. Well the orthotrycyclin was causing me to get server headaches almost everyday if not everyday. So I went to the doctor and told her about my headaches and switched me to mirecette well here I am almost 2 years later and I am still getting headaches almost everyday if not everyday. What should I do? Is their a for of birth control that dosnt cause headaches? My doctor said she dosnt want to lower the dosage anymore because she didn't want me to get pregnant if I'm sexually active. Please help. 
Thank in advance!
