I could use to lose @ 15-20 lbs, but lately it seems that my abdomen (under my breasts above my waist) is swelling, not my waist or stomach area, I have not changed any habits, I am currently taking a class through the gym and exercising 3 days a week, working on it! I was trying some clothes on and noticed it in the mirror, and it just seems an odd proportion to my waist...is this just a 'redistribution' of body fat or something I should be concerned about? Thanks.
