Brief Answer:
Most probably effect of Plan B.

Detailed Answer:
This is more likely the effect of the Plan B.
The bleeding on November 21 was due to withdrawal effect of Plan B.
Also, the delay is due to the Plan B also most probably.
SO do not worry.
Take care.
Please take a pregnancy test just in case.
