I would say there is almost no chance of pregnancy, especially if you don't have sex now for a few days after missing the pill.
Experts nowadays consider a woman still pretty well protected if she only misses one pill, as long as she takes it plus the next one as you did. Such that the current recommendation is that you don't need to do anything special. Best wishes.
I might take Plan B, although I'm not sure it's necessary. It can't hurt.
Since the last time you had sex was Wednesday, taking plan b tomorrow won't be helpful.
I think pregnancy is highly unlikely. I would continue your pills as usual.
You're very welcome.
