What Are The Side Effects Of Loryna Birth Control?

hi i am currently taking loryna birth control and am on my ninth month. i am still having light bleeding during intercourse. a friend of mine told me that it could be that my dosage is too high? is this possible? i take 3 mg-0.02 mg dose. i do not want to switch birth control because i like how this one has helped greatly with my acne, but the spotting during intercourse has been a problem.
