"i have had mirena for 2 weeks now.  i am 18 years old and don&#039;t have any children.  the insertion was very painful for me.  i had cramps for at least 4 hours afterwards once the medicine kicked in.  i have had minor cramps ever since the insertion, but not bad.  i&#039;ve spotted a little everyday.  i wake up and feel like i&#039;m going to vomit in the mornings, but after i am up and eat, it goes away.  i&#039;ve actually lost my appetite and lost weight just in the 2 weeks of having it.  so far i love it! hopefully i don&#039;t have any of the side effects like acne.  i recommend this to anyone!"
