"i&#039;ll have had miranda for 3 years coming this march, 2016. for the first year my periods were irregular and i would cramp up even during times when i wasn&#039;t on my period. this was disconcerting to me but i battled through. at this juncture in my life i&#039;m struggling with adult acne. i&#039;m concerned that the hormones are no longer affecting me as they did for 3 years and perhaps mirena is the cause for this extreme case of acne. i do love this type of birth control and i believe it&#039;s very freeing to not worry about pregnancy while using an iud. there are many side affects and each affect women differently"
