Russian Roulette: Either you want to be pregnant or you don't. The contraceptive pill Sprintec is $9 per pack at Walmart. You can also see Planned Parenthood if your own doctor won't switch you over. Plan B works only if you use it as intended, It only covers sex up to 72 hours. You probably didn't ovulate yet this cycle, so you should be ok. Use condoms until you can start a new pack. Good luck.

Sounds like you: took Plan B four days after first episode of sexual intercourse. Plan B One-Step is up to 89 % effective when taken within 72 hours (3 days) after unprotected sex. It continues to reduce the risk of pregnancy up to 120 hours (5 days) after unprotected sex, but is less effective as time passes. Why are you taking these risks? Recommend consistent use of birth control.
