I had my Mirena put in a month ago. My OBGYN said it was a much better option than the pill, which I had taken for more than 10 years before I had my son four years ago. My body didn't react the same way to the pill anymore so I thought I would try an IUD. The insertion was awful! I had severe cramping and severe faintness immediately afterward. It took about 5 days for the cramping to go away and I got a light period 2 1/2 weeks later which lasted over 5 days (I suddenly felt that THAT was how it prevented pregnancy...it's hard to get knocked up if you're bleeding all the time!) I've had almost consistent low grade cramping ever since...it always feels like those first couple days before my period starts...kinda achely like you know it's coming. What is now starting to bother me is the acne that's COVERING my face. They're tiny little bumps and my face is always greasy. I'm 36 and I haven't had an acne problem in almost 20 years. Now I'm reading about all the problems with weight wain that other women have posted about. I gain about 10 pounds with the pill and that's exactly why I wanted to try the IUD!! I have a hard enough time keeping my weight in check and the idea of gaining more is enough to make me cry right now! I am blown away by the number of posts on this site and I wish I had found it before I had it put in. The information that I was given didn't mention most of these complaints and I know that if I call my doctor she'll tell me to give it a few months (the same advice she gave me with the three different birth control pills I tried). I'm 99% sure that I don't want anymore children but I don't want to commit to a more permanent form of birth control yet. I hope this post helps anyone who's considering an IUD...I would NOT recommend it!!!
