"i&#039;ve had the kyleena for about 4 months. the insertion was virtually painless, as the doctor put numbing cream on me. of course i had cramps afterwards but they went away after a week or so. my periods have been very irregular. when i get my period, i continue to spot for weeks. i&#039;m hoping this will subside. i&#039;ve also experienced acne problems which is something i&#039;ve never had a problem with before. i&#039;m getting acne on my face, back and chest. the string on my kyleena has also recoiled. the doctor confirmed that it is still in place, but i can no longer feel the strings which worries me sometimes. i would recommend kyleena for birth control because it works. there are some side effects but i think they are worth it in the end."
