Low risk encounter with condom slip

[Jameslondon88]

Evening guys and girls. I am a guy who had a low risk encounter with a condom slip. I had sex without a condom for two minutes maximum.
I am a white British male and she was a white British female. A mother, non injecting drug user and I have no reason to believe she is promiscuous, she told me she hadn’t had sex for 5 months before me.
I had a full std check and everything came back negative after 25 days. The lady at the Gum clinic told me they used the duo tests and they are considered as good as conclusive after 28 days, that coupled with my extremely low risk encounter that I don’t need to test for HIV again.
I have had no symptoms, I feel good and well, only symptom I’ve had is a little barrage of bumps appear on my lower back / top of my buttock but in all honesty I think that was down to shaving that area the day before and wearing tight jeans that rubbed in the good old English sun!
I guess my questions are should I just move on?  
Is the test at 25 days being negative as good as it gets for such a low risk encounter?
Many thanks people!
J

I’m obviously no expert hence me coming here but she said the p24 levels if positive would be sky high at 25 days and would of shown, she also said that after 28 days it’s mainly antibodies that will show up in the test, I’m going by what she called an almost zero risk encounter ( I understand nothing is zero risk) but she said with all the info and the negative results that I can be certain I don’t have HIV

Hey, I think you (and everyone else) should do what they're most comfortable with. Yeah, I also think that antigens would have been detected by now, and it's probably conclusive for ~95% of cases.  That would meet MY personal comfort level, but most people don't have HIV, and even if they do, transmission is estimated to occur in 1/2000 encounters, so your overall odds + a negative test mean that it is HIGHLY unlikely you got HIV from this event.

Really? She seemed confident that it was fine at 25 days, she said the guidelines were “ conservative” but the duo will pick infections up in three weeks, her words were especially with such a low risk encounter, the chances she had hiv in the first place, then the chances of me getting it from two mins unprotected, then then chances of negative test as 25 days were practically zero ?

"The lady at the Gum clinic told me ...they are considered as good as conclusive after 28 days". How does this become fine at 25 days?.

You should have followed her advice about 28, so you need to test gain.
