Help! Should I switch my pill?

Cindy

I've been on microgestin 1/20 (21 day pack) for over a year now. The past 4 months I've been getting my period every two weeks which I find kind of annoying. My periods are very light but they las almost a whole week. Anyone who's on or has been on the same kind of pill having similar problems? Should I tell my gynecologist to change my pill to something different? Any suggestions?
