Hi Doctor I Just Made A Mistake Having Unprotected Sex
You can take Post exposure prophylaxis for HIV infection
Welcome to Ask A Doctor
Thanks for posting your query.
Unprotected sex last night. Test for HIV infection will be reliable only after the window period. It will be conclusive only after 12 weeks in case of Antibody detection tests (commonly done). Antigen detection tests will be reliable 3 weeks after the exposure.
But if you have any doubt that you could have got infected with HIV, then you could take Post exposure prophylaxis within 72 hours after the exposure. Consult your physician and start PEP as early as possible. It will abort the infection, if any. Earlier the best.

PEP has to be taken under the supervision of a HIV specialist.
PEP shoud not be taken through online consultation. It has a protocol. You have to undergo a counseling session, baseline HIV test, then the test has to be repeated once in a month for three months and one another test 6 months after the exposure. Drugs has to be taken under the supervision of a HIV specialist. It has to be taken for 28 days. Should not be interupted for any reason and has no value if started 72 hours after the encounter. It will be more reliable when taken within 4-6 hours. In your case it is already nearing 48 hours or more?
Quickly approach a nearby HIV specialist or Dermatovenereologist or a infectioius disease specialist.
