"i&#039;m 23 years old and have tried all types of birth control and always had break through bleeding. i have no children and don&#039;t plan on having them so i my doctor and i decided to try mirena. i had cramping for a day and after that my first months period was 1 day. exactly 28 days later i had my 2nd period very light for 3 days. everything seems to be going well besides the occasional bleeding. i hope this miracle birth control continues to do well. so far it&#039;s the best solution i have found after years of trying."
