"my first mirena was awesome. after my child was born i bled for months non-stop and cramps were unbearable. once inserted within 2 weeks the bleeding and cramping ceased to exist!! getting the mirena only caused mild cramping for a couple hours when it was inserted. i am now going in for my second mirena. i had my 4th child 7months ago and just started getting really bad cramps. it doesn&#039;t work for everybody but i know it works perfect for me. the first time i had it in for 3 1/2 years and only removed it because i wanted another child. i love it!"
