I have had the mirena coil for 2 and a half years. I put on nearly 2 stone within about 6 weeks of having the coil fitted. Cant say I was being careful with my eating at that time but hadnt really needed to before having it fitted. I now have been trying to lose weight seriously and have been exercising loads and eating heathily. My friends who are much slimmer than me are losing weight rapidly but Im not. Just wondered if anyone had any experience of it. Very temted to have it taken out but wonder if it will be worth it!
