Need advice on my anxiety. Hiv from her?

Hi Sir, I had recently had sex with a girl whom I met through a online dating site. It happened a week ago. I knew her from last 3 months and had very good communication with her. She said to be working in a good company in Pune. We went out one day and had sex. I used condom while doing it. But during that time I had a cut in my hand and I had once touched her vagina and also the used condom. The girl is in good health and I even asked her if she is hiv +ve but she told she is not. But i had this anxiety that in my mind. I searched the online sites about the early signs and found that i had little back pain and throat is feeling little strange, I have little dizziness sometimes. Do u think it is possible that I have any symptoms of hiv? Should i look for a common symptom? As i said before the girl is just fine, no noticeable health issues, do u still think it is posdible for me to get hiv from her?
