Igg and I'm came back negative????

[Ithappened]

So I had an outbreak 3 weeks ago, my first ever. I went and had an exam because I was diagnosed with a bladder infection and the pain was just getting worse. Turns out I had 4 ulcers, doctor takes blood and puts me on valtrex for a year. Today I call because they never called me with my results, if it was have 1 or 2 and thenurse said my igm and igg came back negative! I explained to her what I wrote above and she was just as confused as I am and is having the doctor call me. Can the blood work show negative when I clearly had an outbreak? Has this happened to anyone?
