I have a foul odor in my navel (belly button) and now wondering if I have a yeast overgrowth in my gut. Shaking my head.....bc no matter how often I washy bb smells really spoiled. I googled meanings of a smelly bb and it said it means an infection within the body. What kind of infection? And how to get rid of it? I too wonder why this Mirena is causing all these side effects after I've had it out for so long.
