"i have only had the mirena for about 4 weeks and i just got my first period and i have been bleeding so heavily for about 3 days. i already decided that if this continues i will have it removed. i decided to get the mirena because it lightens your period and can totally eliminate it, well that is not happening to me. i know it has only been a month but this is terrible. i have not had any other problems just heavy bleeding."
