"i had my mirena inserted on july 20th, 2015 and since i haven&#039;t had any kids (i&#039;m 18) and wow it was painful. the whole procedure was very quick! i waited longer in the waiting room. the first and second day were horrible, i couldn&#039;t do much because of the pain even after i took strong pain killers. after a few days i still had pain but not as much but oh my goodness my first period with it inserted was the worst, really bad cramping and i bled for like 3 weeks. now after having it for 4 months i occasionally get some random cramps and some times some mild cramps after sex but my period is super light now and i like that part. i am debating whether to get it removed because i have gained weight and my sex drive is just so low now."
