That has nothing to do with this. That is a trial med and it isn't even approved as of yet.

You were given nPEP.
PrEP is short for Pre-Exposure Prophylaxis. It is a new HIV prevention method in which people who do not have HIV take a daily pill to reduce their risk of becoming infected. When used consistently, PrEP has been shown to be effective in men who have sex with men (MSM) and heterosexually-active men and women.
PEP is usually used for anyone who may have been exposed to HIV.
Healthcare workers have the greatest risk. They can be exposed to HIV by:
•Needle sticks or cuts
•Getting blood or other body fluids in their eyes or mouth
•Getting blood or other body fluids on their skin when it is chapped, scraped, or affected by dermatitis
(nPEP)-non-occupational post-exposure prophylaxis
The medication that I am on is PEP
Those scientific studies were found to be flawed. Just because someone has an undetectable serum VL does not mean that their semen VL is undetectable. Prep is given before exposure and nPEP is given after.
I got Prep Medication on the same day when I got exposed. I got exposed on Feb 12 at 1 AM and I took my first PreP medicine on the same day Feb 12 at 7:20 PM
You have a risk but the risk is very low. Scientific studies have shown that transmission is reduced significantly when an HIV + partner is on medication and his viral load is undetectable. Just keep taking PEP as prescribed by your doctor and test 3 months after your last dose of PEP. In all probability you will come out okay.
You are getting your story all jumbled. You aren't given Prep after an exposure.
