AF is due 2/7 - so 6 days. Normally my breasts feel full and a little sore before I start. However, since yesterday my nipples have been extremely sore. I can't touch, pinch, or brush them up against anything without pain. (Not that I go around pinching them, haha, just something I noticed) It's weird because it's only my nipples. My full breasts feel fine. Anyone else experience this before?
