Can Pain Above The Right Breast Be Heart Related?

Six days ago, I woke up with a pain located above my right breast. Since it worsened with movement, I thought for sure I pulled a muscle in my chest.. Since I read most pain occurs in the left side of the chest, when related to the heart, I did not feel so concerned. Now the pain has not lessened, and now I am concerned that perhaps this is not muscular. The pain increases with movements, coughing and deep breathing. I just signed up for health insurance, but have a huge deductible, and is only effective as of today. Basically, I took it out so that I would have coverage for hospitalizations, or catastrophic circumstances. Sure hope I dont need to use it. Could this be heart related, with pain only on right side?
