"i had mirena inserted at age 21, no chidren, had preivously tried every birth control under the sun. insertion was very painful, i nearly passed out. severe cramping lasted for 2-3 days, i was not able to stand up straight due to pain. after that, i cramped for about a week and a half. spotted for the first few months, but it was tolerable. periods had all but completely stopped after 6months. around 9 months iistarted to see an increase in acne. after 1.5 years the acne turned into severe rosacea and cystic acne. i didn&#039;t want to even leave the house - my skin was unbearably flaky and red. i was convinced it was the mirena, though all doctors disagreed. i had it removed and a few days later the rosacea was almost completely gone."
