I'm On Birth Control (ortho Tricyclen Lo) My Boyfriend And

I'm on birth control (ortho tricyclen lo) my boyfriend and I use condoms but last night it broke and he did not pull out.....can I use my birth control as a morning after pill? do I need to go buy plan B? Or should we be fine? I take my pill everyday around the same time and I never miss one. I've also been on this pill for about 6 months now.
