I have recently replace the mirena. It was far more painful than the first time. About a week ago I was confused and disoriented. I am exhausted even with full nights rest. I am gaining weight, urinating more frequently and appetite is up. Tested negative for pregnancy. Tonight check for my strings which at first I couldn t find but then did after noticing where they usually are is a large round feeling tender lump. Behind it was the strings. I look bloated and shaped like second trimester now. So lost on what to do.
