I got Mirena put in on 3/12/09. I had very light spotting for a week or so, then it stopped. Haven't had a period since, and not pregnant. I get cramps once a month, but don't bleed. Once in a while, I will get a sharp pain, like when I was pregnant and my uterus was pushing on the nerve that goes into my leg. That's the sharp pain...down my inner thigh. Told my mother-in-law and she said, "So a swollen uterus, and not period? Sounds fantastic to me!" We all know our uterus swells during our periods, so that was normal. I also have sciatica (sp?) after having him, so that is where the pain might come from. I was told I might have continuous or periodic spotting for up to a year, so I know if it comes back, it's normal. I would recommend this to anyone that has had a child and wants a longer birth control, that doesn't make you retain water and doesn't make you gain weight. It was virtually painless to put in, a little pinch, and I was done! I LOVE IT!
