1. Swollen nodes associated with HIV are generalized and not at one location.
2. 6 weeks negative changing ahead is very very unlikely.
Is there any case neg at 6 weeks turn positive later?
****I'm sorry, I meant have another test in 6 weeks (12 weeks after exposure) to be certain.
6 weeks is highly reliable. Have a second test in another 12 weeks to be 100% certain.
