I've noticed breast soreness on everyone method i've tried. Ortho tricylen, yasmin, and orth evra. The good news is that once your body has a few months to get used to the hormones the side effect tends to subside. There will still be an occasional month where it'sreally bad but for me it's much better than when i'm not taking birth control. So hand in there for a little while and it shoudl get beter. If it doesn't consider trying another type of pill.
