"i had such horrible time with my mirena. i wasn&#039;t instructed to take medication for pain before insertion. insertion itself was painful but as i got home, i was in nauseating pain for 1hr. i finally took a vicodine to be able to ease some pain. i did not have a period for the first 8 mo the after insertion. in the year and a half since i have had the devise in i have gained 40 pounds. i never had weight issues. my mood has turned really aggressive and i loose it over little things. i am depressed a lot  and have no idea why. i had mine removed today and it wasn&#039;t as painful as insertion but i did feel some intense pressure pain during the removal.... i hope this can help someone!!!"
