I have had the mirena for a few years now - this is my second one. I think it is different with everyone - I have had hair loss but that could be my age and its not clumps its just when I wash or brush my hair - a strand or two comes out but I have thick hair so it does not notice ! I have gained weight but I also have an underactive thyroid, I just learn to control my weight. Moods swings well of course Im a woman we all get these ! Im never depressed and I have no periods which is great ! I still suffer with painful sex though - I don't think that will ever change ! Im really grateful that I do not experience the great amounts of pain that other women do on this site - note sure if that's down to the Mirena ? my pain is manageable !

My doctor wants me to make the switch at the end of August to Mirena. Same with you, when I looked at it it was all not-so-happy stories.
I currently have the Skyla IUD, and I still had periods, some painful with it, but I wasn't diagnosed with Endo until about a month ago. Taking that new knowledge into account, I totally get why I was never symptom free, but I did have a lot of success with it.
I've started Lupron injections and was told I had to switch to a hormonal feedback therapy with a higher dosage of hormones to help alleviate the Lupron Depot side effects, which is Mirena.

I used to have the heaviest, longest periods (8-10 days) and the Mirena stopped all the bleeding which has been pretty lifechanging.

I have mood swings and lowered sex drive since the Mirena, but the good outweighs the bad in my experience.

Thanks for the responses! They do make me feel a little better. I know the only way to know for sure is to try it out myself - and if I hate it I can just get it removed. I just wish there were positive stories online
