Levonorgestrel
"Its July 3, 2011 and I got the Mirena on February 25 2011. It did feel very uncomfortable when I got it but other than that I haven't had any issues. I'm still waiting in my periods to lighten up or go away but unfortunately I STILL have them. Not complaining too much because that reassures me that I'm not pregnant. I'm less sexually active compared to before I had it but not because I'm not in the mood its just because I have not had time. I do not feel the strings but I'm going to go and get a pelvic ultrasound to make sure its still there."
