Hi There, About Three Weeks Ago I Had Unprotected Sex.

Hi there,

About three weeks ago I had unprotected sex. Last week I started getting lightheaded and dizzy. I am worried out of my mind. No fever, however I did get a cold two days after the encounter and noticed white stuff on my tonsils which went away a few days later. No headaches, slight swollen lymph node right under my throat but i believe it's because I do have a cold. Everyone in my house has been sick the past few weeks.

The only symptom I've been getting is lightheadedness and dizziness. Is this an early sign of hiv? Please help!
