Sorry to hear about your worries...I can't say about the rash-I would look through these forums and use Google to find out if other people have has a rash incident...I have headaches everyday and same goes for lots of muscle and joint aches...starting to feel like and old lady at 27!It's crazy girl...I'd get it out-I'm having surgery to get mine out this week. Also, I've had my IUD for 2.5 months now and I lost all my baby weight when I had it inserted 6 weeks postpartum and this month I suddenly gained 10 lbs!!! Mirena tricks your body into thinking you are pregnant-hence the weight gain & bloated feeling. Good luck :)
