Are you on anything else that could explain it? Anti depressants and anti anxiety medications are more known for those types of side effects. Sore breasts and mood swings could be the birth control, but everything together suggests maybe something else.
Otherwise, I would go to a doc and ask- it may be something else that you do not want to blow off just because you're on the pill.
Anyway, you should report your side effects even if they are common. Most side effects of b/c pills are supposed to go away within three months or so, if they don't, you should switch so you aren't miserable. But in this case, I'd find out sooner because it doesn't sound good.
