YES, YES, YES!! I have gained over 55lbs since I had the Mirena put in 2 1/2 yrs ago. I am so miserable. Weight gain won't be the only side effect you experience.
I, as many other women on here have had there IUD removed due to the EXTREME side effects. I had mine removed yesterday! Thank god and good riddens! The only advise I can give you is get it out now before it starts to take over your life!
