Hi. I have had a Diva(S) since 5-6 years, but the latest year my period have been heavier and have caused me a lot of leakage. So I have checked a size-guide on the Swedish distrubutorpage and concerning my age and my period they recommend me size L. I can choose between a Mooncup, Ladycup or a Lunette. But I have no idea wich one to choose. Any help/advice?
