Levonorgestrel
"I read so many horror stories about Mirena online when researching whether or not to get one.  Despite this, I went with it based on my doctor's personal experience (having had one herself) as well as the results of the patients she placed them in, which she said most people really liked it.  I LOVE THIS!  It wasn't all that pleasant of an experience when it was inserted, but the pinching pain lasted all of about 30 seconds.  I was completely fine afterwards.  My periods have gotten lighter and lighter and now are officially gone!!  I knew this was a potential perk but I'm so happy that it actually happened to me!  
I HATE birth control pills and am so happy I decided on 
Mirena.  Such a great decision! HIGHLY recommend!"
