Thanks for your query.
Since you have completed 3 months after your last unprotected contact, you can go for HIV ELISA
or rapid test..They will reveal your real status.
HIV will take more time to take manifest. If it is due to acute infection you may get Flu
like symptoms as early as 3-4 weeks after infected exposure. As you don't have such symptoms it may not be acute infection or sero-conversion illness.
Persistent generalized lymph-adenopathy is the next possible manifestation which will always be bilaterally symmetrical painless nodes of multiple sites and will take at least an year to manifest.
like lesions can occur to anybody.
So these are not symptoms of HIV and you need not worry about the same but gat tested for your safety and try to follow safe sex
to avoid such tension.
Get well soon.
