Yes. Check home test: Unfortunately, the plan B drugs are most efficacious in the first 12-24 hours. After that, the efficacy diminishes significantly, and it's not even useful after 72 hours. Considering that ovulation and fertilization happen in a 24-48 hour window that explains why the efficacy would be best in the first day. Check a home pregnancy test. There is also a chance that the pills are delaying your period
