"i&#039;m 16 and apparently the youngest to get mirena from all the reviews i have read. i only got it inserted a few days ago. i have never had children, nor have i ever been pregnant. i&#039;ve also not had much sexual experience, but the procedure was quite quick and really was not that painful. i don&#039;t consider my pain tolerance very high but the pain was very bearable. i got it inserted while on my period. during my usual menstruation i get horrible cramps that will even cause me to vomit, but during the procedure the pain wasn&#039;t even close to that. i felt pretty much normal walking or of the building, no cramping. i even went horseback riding for 2 hours right after the procedure! i immediately noticed a difference in my period. love it!"
