Levonorgestrel
"I've had the mirena since July of 2014. I got it put it when I was 16. Due to have endometriosis it was the best choice. ultimately it was a huge live saver the pain I had before has gone away. The insertion for me wasn't bad but I made a poor decision to go to varsity cheer practice the next day,bad idea. I don't really ever spot on a very rare occasion. I will though if I'm on a antibiotics , then it tends to mess with my mirena and I'll get cramps and will spot. Other then that it's been a good experience so far."
