Boobs have hurt for two weeks!

I have been taking Blisovi Birth control for almost a year now. At this point I expect to not have as many symptoms, but my boobs have been hurting for two weeks now! I always use a condom, except for one time about a month ago (pulled out), but always take my birth control on time. I took a pregnancy test, but it was negative. Also, my birth control stops me from having a period, so I don’t even have that to clue me in. What do you guys think?
