Welcome to HCM.
As you had an unprotected sex (condom displaced) both vaginal and oral with an unknown woman whose HIV status not known and you developed Flu
like syndrome after a month, It is better to go for a HIV test
and rule out this possibility.
A HIV DNA PCR OR P24 antigen test or DUO
test will reveal your HIV status by now.
If you are sure that you are not having HIV then we can get well soon from a ordinary viral fever
Wish you a speedy recovery.
