text: how many emergency comtraceptive do i need to use to evicte the pregnancy?   perhaps the best thing you could do for yourself and your reproductive future is to see a doctor or visit your local emergency/triage clinic.  they will be able to prescribe the "morning after pill" for you if you are still within 72 hours of the sexual incident you are concerned about.  otherwise, i have been instructed that taking the remaining pills in a patient's standard monthly pill pack will also abort a pregnancy, i'd rather see someone like yourself go out and just get the "morning after" solution. you simply take two  contraceptive pills twelve hours apart.  it's relatively simple and while the medical visit might not be convenient, the consequence here may outweigh the other options if you are concerned about an unwanted pregnancy.    good luck, and be safe.
