I'm 34, NP, and I got a Mirena in April. Seems to be working great for me so far! My gyno doesn't do IUD insertions and referred me to someone else who does. I had two months of very light spotting in the beginning of my time with it, and I've had an uptick in acne since getting it. Oh, and some breast tenderness. Other than that, things are fine. I got it to cope with my crazy heavy periods and it's working well for that, plus no babies.
