"i had my mirena inserted 2 months ago.  i am 23 and have never had children, and the insertion pain was not too bad, actually better than my normal cramps.  i&#039;m still having very slight spotting, but no real periods since the insertion, which i&#039;m very happy about because of my painful periods with likely endometriosis. i have a little cramping still, but not bad at all, and its usually only when there&#039;s pressure on my abdomen, like when i&#039;m working out or need to have a bowel movement.  also, i had to go on a non-estrogen form of contraception because i have migraines with auras, and i think these is a great alternative to oral contraceptive pills!  as a medical student, all the ob/gyns i&#039;ve worked with have talked about the benefits of mirena."
