Birth Control and Side Effects

So I started taking the pill as my form of birth control. I have been popping the pill for three months/cycles now and there are side effects I have noticed that wont go away and Im not sure if anyone eles has the same side effects. One of the biggest side effects is breast soreness. Its not like your average breast tenderness that most get around their period...its like severly painful. Sometimes it feels like a stabing pain or like something is trying to explode out of my boob. When the pain is not so bad...it constantly feels like its badly bruised. I cant hug people or even take a shower and wash them gently..thats how bad they hurt! I would compare it to a mother who is breast feeding and she is super engorged and she has breast pain. Thats how i feel. Then my hair has gotten so thin a brittle. has anyone had these effects taking the pill?
