Yaz? PillπŸ’ŠπŸ’ŠπŸ’ŠπŸ’Š

My doctor prescribed me yaz because i asked about birth control. But i have read about Yaz that it is for Pcos? I don't have pcos, i have regular periods and everything.

I don't understand? I just wanted birth control not medications for something i don't have.

Someone?
