"i have had mirena in for a little over 7 months. i love it for the fact i have not had a period for the entire time, just a little spotting for about 3 weeks after insertion. but i cramp pretty often still, but at my checkup the doctor told me if i could just make it through the first 6 months i would be good to go. but i&#039;m still hurting pretty bad. i hate to keep taking medicine because i know it&#039;s not good for my body. i am tired of cramping all the time, because at times it&#039;s so bad i feel like curling up in a ball and sleeping all day.
