"i&#039;m 17 and i had my mirena inserted today. i&#039;ve never had a child nor have i been pregnant. the insertion only took about 4-5 minutes. yes, it was painful but not unbearable but that was only because i&#039;ve never had anything in or out of my cervix other then being on my period. i had cramping, but because of the ibuprofen i fell asleep as soon as i got home. when i woke up all the pain was gone. the experience was uncomfortable but overall it was a fast easy process."
