I had Mirena put in a week ago and couldn't stand it, so I took it out myself last night! I'd never had issues with bad body odor and was perspiring terribly just a few hours after a shower. Also, those so-called "strings" were very painful at the ends, since they were digging into sensitive tissue.
I didn't want to wait and see what other symptoms would occur and just pulled it out carefully.
I got on my knees and relaxed and pulled on the strings very slowly.
I feel fine now but still a little bleeding.
I'll post again soon with an update on how this went.
