Brief Answer: Hi and welcome to XXXXXXX Detailed Answer: Thnaks for the query. The risk of HIV transmission by oral sex is very low and you should not be concerned. Of course, it is possible but chances are less than 0.5 per 10 000 exposures. so this is almost negligible. Other std can be transmissed but these usually manifest with genital changes,lumps,rash or penis discharge. Acute retroviral syndrome is rarely seen after only 4 days. Also symptoms of ARS are nonspecific and usually it has nothing to do with hiv. Mouth ulcer can be caused by various conditions including stress, resopiratoty infections, mouth injuries,irritation and many others. HIV is last thing to think of. So just dont worry. If you have any doubts about her HIV status you can do Hiv testing after 3-4 weeks,but I dont think it is necessary at this point. WIsh you good health. Feel free to ask. Regards
