The only risks for HIV in adults are:
1) Having unprotected anal or vaginal sex, or
2) sharing intravenous needles with IV drug users.
You really didn't have a risk, so I am not sure why you are taking PEP. There are no exact statistics for PEP efficacy, but it's estimated at 80-90% effective - it's highest when taken every day for 28 days, and started within 72 hours of an event.
Your medical symptoms have nothing to do with HIV. You would NEVER get symptoms that soon. It's just not possible.
Again, you didn't have a realistic risk for HIV.
