plan b effectiveness?

k so i had unprotected sex on monday. im on the pill but because of antibiotics, it was reliable for this past month. normally me and my boyfriend use the withdrawal method and works fine but this time he may have came a bit early before taking it out and were both not sure. i didnt think he did but as a precaution i took plan b today. (approx 50hrs later) my question is how effective will it b and do you think i have any reason to worry?

    I explained this the other day so I'm repeating myself. ;) You have about a 30% chance of getting pregnant without protection. Plan B has an 85% rate of effectiveness. Therefore, you have a 115% chance of not being pregnant. Don't worry.

    After taking the Plan B pill, you will start your period, effectively cancelling out any chance of pregnancy.
