Did you use protection? Plan B is not a form of birth control or they would prescibe it to women to take after each sexual encounter. Unless they have begun doing that already.
Why not get on a reliable birth control?
why would you wait so long to take plan b. the longer amount to time it takes you to take it. it lessens the effictiveness of it.
if you had sex and had unprotected sex at that (im asumming you did) then yes you can be pregnant
clearly on want to be pregnant but using plan b is not a form of birth control. so GET ON SOME!
