"* 3 month update* got my kyleena iud on 7/17/17, so far its been great. i have had one issue with it. it was moved during sex one night and caused severe cramps for about 10 mins, had to take 2 extra strength tylenol to even touch the pain. slept off the pain and was fine the next day, called my doctor to ask about the experience and she said i was caused from the position during sex and it is something that can happen. i am currently near my next cycle time, i haven&#039;t had any bleeding but i am super tired and achey. my last period was light spotting for about a 12 days, no cramps. so far its been great."
