In brief: Could be

If your talking like not long after 72 hours.
You could try it up to 4-5 days, it won't cause a birth defect or an abortion, it changes the uterine lining to avoid implantation.

In brief: Much less effective.

Plan B One-Step is up to 89 % effective when taken within 72 hours (3 days) after unprotected sex.
It can reduce chance of pregnancy by up to 95% if used within 24 hours. It continues to reduce the risk of pregnancy up to 120 hours (5 days) after unprotected sex, but is less effective as time passes.
