I had my mirena places in bout 4 years ago i've had a several issues with this thing starting with my period after a few months i stopped having periods then the strings would poke my boyfriends penis and we decided to go back to the doctors office and take it off she talked us into keeping it and she would cut the string a lil shorter and a few nights ago i touched to see if i still had the string i did but it came out with like white skin should i be concern?? Has it happen to any one else??
