Period/birth control pill

Morgan
I'm on the ortho-tri cyclen lo birth control pill and I forgot to take a pill but I remembered the next day. So I took two the day after I missed the one pill. And I wasn't on my period before I missed the pill, but now I started. And I wasn't starting the day after I missed the pill. But I'm starting now. Why is that? I was supposed to start on the 26th of this month. So now I won't or will I still have that period? I'm confused.
