In theory, if you would have ovulated soon after taking plan B, no. That's the primary mechanism by which it works.
In some cases people ovulate anyway; there are secondary mechanisms to prevent pregnancy. And I believe it would be normal to ovulate later... I haven't taken it. It can screw with your cycles for a while, though.
