No, that is not common. ARS usually starts within the first month and doesn't last longer than a few weeks.
If you get tested now you will get an accurate result.
The Acute HIV infection symptoms usually occur the 2nd and 4th week post exposure!so from my general knowledge NO I don't think so!
So after ARS symptoms there shouldn't be any other symptoms like diahrrea, muscle weakness, tingling or anything like that??
if you are at 4 months, why not get tested?
i got tested at 11 weeks and 4 days and the results were negative
you are negative! goodbye!
