Forgot to add she had rashes she claimed where psoriasis all over her. I think I remember some on her hands, could that have been a exposure.
You had no risk. If you take an HIV test, which is unnecessary, you can expect a negative.
In an adult, only unprotected anal or vaginal sex and sharing IV drug needles with infected users could possibly result in infection.
You were never at risk. Even for some one with a real risk, 13 week would be conclusive. We can't endorse what other websites are telling you, here we offer practical information.
This is internet, anyone can say and claim any thing, fact of the matter is, no one has ever reported to get this infection from recieving oral sex, saliva restricts transmission.
You are clearly being paranoid about this event, you are worried about a total no risk scenario, although you didn't need to test, yet you can't accept your test result.
We have offered you the best we can from here. Perhaps seeing a therapist for your paranoia would be a good idea, if you can figure out what's exactly the cause of this anxiety, you will be able to overcome this ordeal. It is mostly observed that guilt is the number one reason for such anxiety followed by fear, that's another factor known to create such situation amongst worried wells.
Good luck.
