"i have been on the mirena for 10 months now. i am going to take it out as soon as possible. the cramping has indeed gotten worse and i bleed at very odd times; sometimes very heavily with clotting and sometimes lightly. it interrupts sexual activity from the bleeding and i run back and forth to the doctor because i can never find it. honestly, it was good in the beginning, but i feel like these symptoms should be gone by now. just goes to show everything isn&#039;t for everyone."
