If this gal had genital herpes, you will not get it from her performing oral sex on you. If she had oral herpes and performed oral sex on you, there is a risk but even that is low.
Your symptoms do not sound at all like herpes. Hsv1 genitally which is what would be the risk from oral sex also do not typically cause symptoms this often and this long and drawn out. You should continue to follow up on this with your regular doctor and an urologist but it's time to put herpes as a possibility away. Normal mouth bacteria aren't always so normal in the genital tract and can cause things sometimes.
