Do Levlen Pills Taken At Different Times Prevent Pregnancy?

ive been taking levlen ed pill for possibly two months or so now.
i was taking cilicain vk phenoxymethyl penicilin a week and a half ago, but continued to take pill. i take the pill at an unregular time each day as im a very busy woman.. last night my boyfriend came inside after a ripped condom.
what are my chances of being pregnant.. is the levlen pill still effective if taken every day but at different times?
