Management of Initial Bleeding/Spotting Associated With the Levonorgestrel-releasing Intrauterine System (MIRENA)

The purpose of the study is to investigate if the study drugs (tranexamic acid or mefenamic acid) can control irregular bleeding during the first 3 months of using Mirena. The study drugs tested are tested against placebo ("dummy medication not containing any active drug"). Treatment period is followed by a one-month period when study drugs are not taken but Mirena use is continued.
