hi im a 16 year old female and when i was getting ready to take a shower i noticed both of my breasts have a pinkish red spot to the side of the nipple. also last week, my nipples started burning so bad that i had to rub vasoline on them to soothe the pain. ive always had small breasts, barely a b cup, so could my breasts just be growing? or do you think its something else, maybe cancer?! i also started my period this morning but i have never had any symptoms more than slight cramping for my period. is this something i should worry about???
