Side effects vs STI: Some women notice that their periods are off in timing +/- 2 days after taking Plan B. It is often the next month's period that is heavier or longer, not the current one. In your case, I suspect you had unprotected sex (hence the need for Plan B) and may be experiencing pain from a pelvic infection/ STI. You need to see a physician for STI testing and treatment.
