Hi L.,
BC pills often take 3 months to get used to. That said, if it's driving you crazy, ask your doctor to change your pill. Tell him/her about your side effects. Hormone levels in specific pills are often known for certain side effects. For example, I cannot take a tri-phasic pill, such as Ortho tri-cyclen, because it will give me awful migraines. Every woman is different which is why there are so many options!
Best of luck!
