Mirena

I'm thinking about getting on Mirena for a variety of reasons. I do have a history of ovarian cysts, but have not had any pain since about the second week in January. I'm on birth control, I don't have a problem taking it, but I'm not ready for kids, and I hate having my periods, not like other women do as well. Has anyone had it? Did it feel comfortable? Not comfortable upon getting it inserted? Pros and cons would definitely be appreciated. :)
