birth control
"I haven't had Mirena very long, but so far I have had a pretty good experience. Getting it put in was pretty painful like a lot of people have said, it doesn't last that long though, and being on your period at time of insertion makes it easier. Afterwards I had pretty intense cramping for the rest of the day, I would make sure you have nothing to do afterwards because it really helped my cramping to be able to just lay down and relax the rest of the day. The second day I had some mild cramping, but nothing too bad and the third day I was almost back to normal. I have not had any bleeding since I've had it inserted, nor have I had headache or nausea. My boyfriend could not feel it during sex and neither could I."
