My wife had her period on 09/10/16 and it ended 17/10/16 and she is now having some light blood flow 24/10/16.please is that something to worr about o?

Not necessarily: The first period is longer than some people but not abnormal- depends on what's usual for her. The spotting mid-cycle can be due to stress, other women's cycle, missing/ being late with birth control, or other passing reasons. Consider a pregnancy test. If it doesn't go back to her usual by next month, then she should get it checked out.
