Have never tried it myself...lol But here's what the experts say.... If you take the pill within 72 hours after you've had unprotected sex, levonorgestrel can reduce the risk of pregnancy by up to 87% if taken as directed. If you take Plan B One-Step within 24 hours, it is much more effective. But you should know that Plan B One-Step is not as effective as regular contraception.
How would anyone be able to answer that question from personal experience? The idea is that you take it within 72 hours so how would you know if you were pregnant at that point? UGGGGH...... Look up the research
