My period is lasting too long after taking microgynon 30, is it normal?

Menses: Yes and no. Yes, it is normal for changes in the menses to occur in young women snd those taking oral contraceptives. No, it isn't normal if it bothers you.

Not sure: Need more info to know if it is normal. How many days are you bleeding? What day (in your cycle pack)do you start bleeding? With this additional information, we can give you a more specific answer
