"i love mirena. i am 20, and have no children, but i had it inserted about a year and a half ago now. the insertion process was quite painful, and i had cramps the rest of the day. but since then, i have not had a period, or even any spotting. the only down side is that i have gained about 25 lbs, but with some strict dieting the weight is starting to come off slowly. overall, i love it!"
