Lymph Node uestion

I'll get right to the point:

My lymph nodes around my body have been swollen since ~mid July. I've gotten three HIV tests since then: one around the time of the symptoms, and two at the end of August.

My last possible exposure, at the absolute latest, was around the start of June.

My question: do lymph nodes start swelling before or after a positive result on a test? AKA - do lymph nodes start swelling once they recognize the virus?

All of my tests so far have been negative btw.

If your last test was three months post exposure then you don't have HIV and your swollen lymph nodes have nothing to do with HIV.
