I’m anxious about this

Four years ago I had my first sexual activity with a female sex worker, I received oral and vaginal sex, both using condoms, I did not had any kind of fever or cutaneous eruptions at the time
I spent all this time in celibacy
This year, I started dating and had unprotected sex with my girlfriend who was a virgin
What are the odds I am infected with HIV, or worse, what are the odds I transmitted it to her?
