"i had the kyleena inserted about 4 months ago and i am very happy with the results. i am only 18 years old and have never had sex or children so i will say the insertion was incredibly painful because i am not used to anything going inside me besides a tampon. the cramps afterwards only lasted that same day and were bearable and pretty much gone 24 hours later. i have only had one period since the insertion which was the whole point of me getting it because my periods came more than once a month and were very heavy. since getting kyleena i have very dull and barely even painful cramps during a period and not as much vaginal discharge either. i will say periods become a bit unpredictable but i haven&#039;t even had it a full year yet."
