Suggest Remedy For Abnormal Menstrual Bleeding After Taking Levonelle Tablet

Hiya, I took levonelle on the 21st of December, started bleeding a week later so I started the pill (microgynon) the first day I started bleeding... i have been bleeding ever since, through the whole 3 weeks of the pills and now I'm on my break and still bleeding. There has been no end! Is this okay or should I be concerned about the amount of bleeding? I know levonelle can cause bleeding but I thought it would stop especially when I'm taking the pill aswell. Any advice appreciated :-) thanks
