I had sex unprotected sex and I took PlanB the next day. Now one week before my expected period day my nipples are so sore, hard and kinda hurt, but not my breats. I have had times were my breasts get a little heavy before my period but not this. My sister does have her 4 month old boy around a lot; I don't know if that has anything to do with it. What is going on???
It's probally the pill, and the combo of getting ready to start. You can have nipple soreness before and during a period:)
