If you are on birth control and also took Plan B correctly, it's unlikely you are pregnant. To answer your the question, yes, emergency contraception can cause your periods to be irregular. Side effects may include changes in your period, nausea, lower abdominal pain, fatigue, headache, dizziness and breast tenderness. Some women may have changes in their period, a heavier or lighter next period, or a period that is early or late.
