"i had mirena placed today. i took the recommended 800mg of advil. the pain was horrible at insertion. now keep in mind, i am 33, and have not been pregnant. the pain didn&#039;t last long, but will forever haunt me. it had been 12 hours since insertion. cramping is almost gone, but i do feel bloated. not much appetite, which is good! i just wish they would have warned me about the discomfort of insertion. i have access to strong meds, do to other health issues, and could have medicated more appropriately. time will tell is i like ot. i have been on birth control since i was 16ish. i have done pills and vaginally rings prior to this. i hear good and bad about it, but staying positive."
