I have been on birth control for one month, full. I'm on my second pack and I have one last pill, it's tonight pill. I haven't started yet. I started last month on the 20th and I was second to last pill on that one. Today is the 18th. Will I start late? Is that bad?

I have taken plan b while I was on birth control this month. I took it to be on the safe side. Is taking the plan b might be the reason why I'm not starting?

Thank you.
