In two months i have went from a size 7 to a size 10 and went up a cup size(bra size duh) I have a tummy, and it started off with a little chubby tummy and then under my breasts in the center got hard. Then about 2 and a half inches under my belly button started getting harder on and off. I look like I have gained weight but the scale still says I weigh the same. What is going on?
