Does Plan B work 22hours after unprotected sex. Only pre ejaculate and on most fertile day?

Yes. For it to be effective, it needs to be taken within 72 hours of unprotected intercourse. Expect that you will experience some confusing breakthrough bleeding and a delay in your next cycle. Also, check a pregnancy test in about 2-3 weeks.
