"i had mirena for one year and 2 months and finally call my ob to remove it yesterday. it works great if you don&#039;t want to get pregnant. and it doesn&#039;t affect my sex drive at all. but began having few cramps after i work out and break out a lot, that i can&#039;t tolerate any anymore. i&#039;m on pills right now. my ob told me that pills will clear my acne. so hopefully it does."
