"i have had my mirena iud for 2 years now. the insertion was something i was not prepared for. i wish i had been sedated. heavy cramping and bleeding that entire night and next day. i am a rn so i wish i&#039;d have been forewarned because i had to work the same day i had it inserted. word of advice take the day off, rent a movie, and vegetate on the couch. i had to have an ultrasound because the strings vanished into thin air. but other then that no issues. i love it. i no longer have the crazy mood swings that i had with the birth control pills. i have no children. no weight gain i can associate from the iud. i will occasionally have periods of spotting. no side effects. worth it."
