I Just Need To Know My Chances, I Had Oral

I just need to know my chances, I had oral sex with a girl a few months ago and I'm not sure if she had HIV or not. I got diagnosed with a URI about 6 days after it occurred. There was no unprotected sex and I have had sex with her before with and without a condom. My most recent test was a negative but it was in January and I took a at home test recently and its also saying negative.
