Questions!!!!

My girlfriend is infected with HBV. We make protected sex for many times. I was tested my HBVang and HBVantibody.
HBVang                                   Negative
HBVantibody                             Positive (11.7 Ul/l)
I took my booster vaccine at last month (19.9.2009). But in this month (10.10.2009) i have got abdomenal (abdominal) pain from right lower side. My urine are yellow as gold. I took ultrasound at last 3days and the result is normal liver and nothing wrong with my abdomenal (abdominal) parts. The pain was gone but the urine color is still here.
Here is my question...

Can i be infected with HBV?
How long should i wait to test my antibody (+ or -)?
Is there window period for HBV testing and could you tell me how long??
Can my urine color be Symptom??
thx
p.s. sorry for my poor english

If you feel the symptoms, get tested again. If it's HepB it will show.

Many many things affect urine color.  This doesn't tell you much.
