I have had mirena for the past 4 years. I have had the diarreah, cramps, and nausea every day or every other day since I had it put in. I wasn't having these problems before I had it and the docs keep telling me that it can't be the mirena that its just gas. I've tried everything and I'm just miserable and hurt all the time. I can barely walk away from a bathroom before I have to go back in. I feel so nauseated that I want to throw up but rarely ever do. The cramps are worse than my labor pains were. I'm going to get it taken out and well see what happens. I just want ya'll to know you are not alone.
