"i was on mirena for a little over 2 years, starting in 2014. after about 7 months on it my period stopped, and that (in many ways) was my favorite part of mirena. unfortunately, around this same time i started getting intensely painful (but benign) ovarian cysts. the day before thanksgiving, 2015 i had a cyst so painful that i was convinced something had gone wrong with my appendix. all told i went to the er three times due to these cysts (yes i&#039;ve had the hpv vaccine). finally i took it out, and in that time i&#039;ve had no pain. i&#039;ve also lost about 10 lbs of the weight i gained on mirena. i loved the convenience, but some things weren&#039;t worth it."
