I have had extremely sore breast for almost 2 months now, and have been having pains
in my
stomach and pelvic region as well as a little bulging
in my lower stomach. I had to buy new jeans! When I looked for reasons for this, all the came up was pregnancy (round ligament pain), and cysts. The cyst could explain the breast pain and pain in the ovaries and possibly even the weight gain, but that it. And it said they would be detected during a pelvic exam, which I already had.
