Is it too late for this cycle?

We started TTC again last month and I had a very weird cycle.  I O'd much later than expected and started AF much earlier than expected.  I have been reading about Luteal Phase Defect.  My LP was only 9 days last month.  I don't know if this is going to be a recurrent problem or if it was just a "one month" thing...but here I am CD17 and I still haven't O'd.  :(  

I have read about taking B6.  Is it too late to start that for this cycle because I should O any day now?  If I went and bought some today, would it make a difference or should I have started it at the beginning of my cycle?

Any thoughts or experiences would be appreciated!
