I had Mirena put in two weeks ago because I was told this will not affect my heart or give me major side effects like the pill or Depo does. HA! I have not stopped bleeding since, I've had cramps, been extremely angry (more than usual), and now I want to eat all the time too. I had been doing Weight Watchers to try to lose weight and had lost down to my pre-pregnancy weight and then had Mirena put in. Now that I want to eat all the time, I don't have any desire to try to lose weight. I just want to eat. I can't even have sex with my hubby because of the bleeding, and does anyone else still feel the strings? I looked up the Mirena website and it says of the two threads, one is made of some sort of poly-substance and the other is made of iron oxide. Um, that's a metal and I'm allergic to metals. I feel the threads ALL THE TIME. It feels like a burning sensation to a ripping sensation on occasions. Believe me, I even feel it when walking, which makes it difficult to want to exercise. Because I can feel the strings, I don't want to have sex because I'm afraid it will hurt my hubby. I'm calling my doc today to have mine removed. I'll just have to use condoms from now on because Depo destroyed my body last time I was on it and the pills mess with my heart and make me crazy.
