Brief unprotected encounter

Hi,

I hope you can help me, I recently had a very quick encounted of unprotected vaginal sex with a relative stranger (she was a 38 year old caucasian, I am a 30 year old caucasian). When I say very quick, I mean it was literally in and out once and I pulled out.
We did have prolonged oral sex though.

I am very concerned that I may have contracted HIV, I have phoned an HIV helpline and they said the risk is very low but I would like to get a second opinion from you. I wouldn't normally be concerned, but this is the first time I've had a sexual encounter with a relative stranger in my whole life.

What do you think the chances of me having caught HIV in this brief encounter? would you recommend me get tested?
I recently had a STI checkup and was negative on all, although I didn't have an HIV test.

Thanks very much in advance

3 months is conclusive for hiv testing you had a brief unprotected incident female to male is 1 in 2000 episodes for transmission of hiv not saying you cant get it from a 1 time exposure yes it happens. I would not be yoo concerned here oral is veryyyyyy lowwwww risk
