Hello there ~
I am not sure as to what advice you are seeking. If it is about whether you can continue to have sexual contact with your partner, the answer is yes but there is a very small chance that you could get the infection in the future due to any circumstance that is not under your control, e.g. a broken condom, etc. If you question is if the drugs that she started today will be effective, the answer is yes, they are effective in curbing the multiplication of her HIV
but will only make them dormant, we still do not have a cure for HIV, so she is less likely to transmit the infection and become sick herself. If your question is about your chances of having HIV, I recommend that you get yourself tested every month for the next 3 months and then every three months due to your risk of having been exposed to HIV from your partner.
I hope this helps. Take care and have a lovely day !
