My doctor recommended the Mirena progestin-releasing IUD to me. I have never used an IUD before, but I'm too old for the pill now. Plus, I'm a smoker (trying to quit).

I'm just wondering if anyone has any experience with this product. Did you have side effects? Was it effective? My sister got pregnant while she had an IUD 14 years ago, so that concerns me a bit. I got pregnant while I was on the pill, though, so maybe we're just especially fertile. I dunno.
