I have experiencing breakthrough bleeding for the past 3 days and i am currently on aleese which is a low dosage birth control pill. This is my fourth month on aleese and during my third cycle of birth control i decided to skip my sugar pills to skip my period. this is when the bleeding started. i havent missed any pills and i am sexually active, but 2 weeks ago i took a pill 4 hrs late. I am wondering why i am experiecing the bleeding and how can i stop it?

Thank you for your help.
