I am a guy and I had a sex with some random girl without condom. She is not a sex worker and only had 2 or 3 times of sex she said. I know it couldn’t be true or not. I give her some oral sex for few seconds, 1 min maximum and I was finished without inside her vagina as It was my first time experience and it only lasts 1 or 2 minutes for 3 three times on 3-march 1AM, 2:30AM and 5:30AM. I took a PEP (dolutegravir 50mg, Lamivudine 300 mg and tenofovir 300 mg) on 91 hours of first exposure and now I am scared of HIV and syphilis. Before taking a blood test it was completely negative and now I have a plan to test duo after 28 days of PEP finished.
1. What are the chances of protecting with PEP?
2. I can have hiv or syphilis in my current situation or not?
Now I am in my one week of exposure and no other symptoms are happening except from some mosquito bites itching since our country is in Summer.
Please help me with suggestions doctors
Thanks in advance.
I am sorry if my english was bad
