Depends: Combination pills, or any pther method except abstinence, are not a 100 percent safe. Best of luck.

Close to 90%: Levonogestrel pills, including the brands Plan B one-step and Next Choice one dose, are up to 89 percent effective when taken within 72 hours (three days) after unprotected sex. They continue to reduce the risk of pregnancy up to 120 hours (five days) after unprotected sex, but they are less effective as time passes.

Low: If i'm understanding your question, it sounds like you are taking combination birth control pills, and took a pill 2 hours late. If you have been taking the bcp every day then being a few hours early or late with your pill will not impact its effectiveness.

Thank you...if that is the question, I misunderstood. Thank you Dr Jones!
