"i had the mirena inserted 7 months ago. i took 800 mg of ibuprofen beforehand and experienced only minor pain upon insertion. i had some mild cramping throughout that day, but afterwards none. i still have fairly regular periods--every month, light bleeding with a little bit of cramping. i was told that after about 6 months my periods would probably disappear, but i&#039;m still waiting for that to happen. no weight gain, acne, or change in mood or libido. i love it! very satisfied."
