Hello, recently (well September) I had the Mirena IUD fitted. I have recently came of my period after it beginning straight after it being put in... which was pretty much constant bleeding. This last week I have been expiring, loss of appetite, bloating, urinating more than usual, feeling sick and cramps. Even though the IUD is contraception, This let me to believe pregnancy, however I have taken two tests and they have came back negative. Please can you help?
