The risk of the type of exposure you describe is fairly low- but obviously not 0.
Without PEP, anal intercourse - the riskiest thing you describe- has a risk about 0.5% per sex act. IN some people it can be higher, if the infected partner has a higher viral load, or there is more trauma, blood exchange, or other concomitant STDs.
PEP is thought to lower the risk by at least 80%- and likely more with current multi-drug PEP. Unfortunately waiting 30 hours later lowers the benefit rather substantially, so I am not sure how helpful the PEP would be.
Overall , the risk is low- but obviously you should have follow up testing at 4-6 weeks, and 3 months.
Always ask if you need clarification/more information.
POSITIVE feedback & a BONUS are warmly appreciated. Please note that answers are for information only, do not take the place of an IN PERSON assessment by your doctor,and does not establish a patient-physician relationship.
The sooner it is started the better.
The concept is to start before the virus attaches to receptor cells, and potentially incorporates into your DNA.
Beyond 24 hours the effectiveness is likely questionable.... although recommendations do not say not to use it, in high risk cases even beyond that. But based on animal models it is unlikely to be effective beyond 1 day.
At this point, I would probably continue.
But like I noted, the benefit is minimal.
This may be something to discuss with your doctor/ or preferably an infectious diseases doctor in person.
