Took plan b (w/in 9 hrs of intercourse) on same day as expected period, bled for a wk (same amt as period) should next period come at its normal time?

Plan B effects: Plan B can effect more than one cycle of menses. It is possible that cycle will be disrupted. Check urine pregnancy test 3 weeks from date of unprotected sex to determine if pregnant. Plan B is 95% effective when taken within 24 hours of unprotected sex.

Next cycle: Likely Plan B was successful and you should have your next menses as expected. Use birth control and protection against STIs if you continue sexual activity. All the best.
