Help! What are my risk of being positive?

About 5 moths ago i had an encounter with a lady with unknown hiv status, I fingered her for a few seconds then i took my fingers out her vagina then shortly after i put them in my mouth and sucked on them, and i had a cut on my tongue when i did it that occurred 20 minutes before the encounter. I also used mouthwash sometime before the encounter it was before I bite my tongue . Around a week or so I had a headache and sore throat that lasted for a few days, at exactly two weeks i had diarrhea and vomited once. Dont think my lymph nodes were swollen at any point, no noticeable rashes and I have had continuous stomach discomfort for about 5 months which occurred not to long after reading symptoms at about a week and half after contact. I had an hiv test done at a clinic at about two weeks and half after the encounter test were negative but through research test are not conclusive until 3 months. So what are my chances of having HIV?
