Ive had 2 recurrences.  I was diagnosed June 2007, then again April 2008, and the third time June 2009.  The first recurrence I had an awful feeling.  I just knew what looked like a cancer sore almost exactly where my original tumor was that it would turn out to be cancerous.  It was a hunch.  I did not feel sick at all.  The second recurrence I had never felt better.  I went on a 25 mile bike ride with my son and then was told I had Stage IV OC.  I was told to get my affairs in order.  
A recurrence is just like any other time a person gets cancer.  They same symptoms would be for the first diagnosis or a recurrence.  You have the 
HPV+ on your side.  
HPV+ patients usually respond better the radiation and have better odds against it coming back.  With it being so quick, it seems to me (of course Im not a doctor) like the radiation did not completely kill the cancer.  Im sure you are worried and when facing a possible recurrence the mind will automatically go to "what if".  Do your very best to stay busy to keep your mind off the possibility of being sick again.  
When I first was told I may be having another recurrence in 2009, I decided right then and there I was not about to waste any time worrying.  I pushed myself to stay busy and to go out and do all kinds of activities with my children.  I realized how much time was wasted by worrying what the test results would be.  Worrying will never change a test result so I went out and enjoyed myself.  Its not easy to make yourself so busy you cant worry but I got pretty good at it.
If and that is 
IF this would be a recurrence for you then please dont panic.  You are already ahead of the game by knowing the medical jargon.  When will you get the results?  
If it is a recurrence please get a second opinion at another cancer center.
Best wishes!
