"i had my mirena inserted september 2011, background info: im in my twenties and have 1 partner and i have not had any children. my doctor wanted me to try the nuvaring first but i said i&#039;d like the mirena for ease of use. the insertion was uncomfortable, and i had some cramping that day but nothing you cant handle! :) overall, i like the mirena. i have spotting off and on, but i only need a panty liner when it happens. no acne or weight gain, i do have a decrease in libido and i find that if i have an orgasm it is painful as i get cramps after (maybe that increase my decrease desire? due to expectant pain...). i&#039;ll be keeping in the mirena for another year to make it to the 5 year point, but ill be removing it then."
