If i took plan b everyday last week i dont have my period yet i had sex tuesday wednesday didnt use protection could i be pregnant ?

Everyday? See doctor: Plan B can alter the menstrual bleeding for the cycle in which Plan B was taken, and sometimes the next cycle too. There can be irregular spotting. One should be sure to check a home pregnancy test about 3 weeks after sex, because Plan B works most of the time, but not all the time. Plan B works less effectively if taken more than 2 days after sex.
