My breasts are scaring me!

I'm 3 days away from expected af. Been ttc for 14 months. About two days ago my breasts got sore. It's weird because they really only hurt in the morning and at night. Soreness has increased and I noticed my right one is much more swollen and in much more pain than my left. I rarely have sore breasts and it's normally during ovulation and a hell of a lot less painful. Anyway, I checked for a lump. I haven't found anything to really worry me but omg I feel the need to massage my right tit. Wtf is going on?!? My left is a little sore but not nearly as noticeable. Please please comment opinions or ideas or similar stories before I go to my doctor frantic.
