Large bruise on my breast

Lauren

So, I have a pretty decent size bruise on my right breast. I just noticed it early this morning although I did not see any sign of it whatsoever before then. It’s almost as if the outer rim of the bruise is a yellow color, & more toward the inner part of the bruise is purple/dark red. I tried to recall if I may have bumped into something to cause it, I just cannot remember doing anything! The bruise does not hurt at all. There is no tenderness that I have felt so far. Also, I do not feel any sort of lumps... it’s just the bruise. I know I might be over analyzing this, but I just feel a little weird & concerned about it. I attached a photo that you can view. Any thoughts/opinions are so greatly appreciated! Thanks y’all.
