I had my mirena put in almost 7 months ago. I had my first child 1 year ago and chose to use Mirena because I'm terrible at remembering to take the pill. The procedure didn't take very long but I thought it was painful during the insertion it felt like a contraction during labor. I cramped and had lower back pain for the 1st week. I swore to my husband I was going to have it taken out because for the first 3 months if I wasn't having a period I was constantly spotting. I was convinced the reason mirena prevented pregnancy was that you weren't interested in intercourse with all that going on down there. It has stopped finally. I do have a period every month it is slightly lighter then what it normally was, which was pretty heavy, but some periods are worse then others as far as cramping goes. Intercourse is not painful. I have noticed I've been just a little more emotional and it varies depending on what time of the month it is. I'm okay with mirena so far. So I'm going to decide to keep it for now. But it does sit in the back of mind that if at some point I suspect Mirena is causing any kind of harm to my well being I will not hesitate to have it removed.
